F*CK IT,
DO IT.

Introduction: Before We Begin

I used to be someone who made things happen.

Not in the hustle-culture, grind-until-you-bleed sense, more in the quiet, almost magical sense where I'd decide I wanted something and it would simply... appear. I'd dream it, and then it would come to fruition. Career moves. Adventures. The next chapter. I was, without really having a word for it, someone who operated on a principle of: I want this, so I'll go get it.

That was in my twenties. Earlier, too, in my teens, I had this quality that I didn't know was rare. The world felt open. I moved through it with a kind of natural confidence that I didn't earn and didn't question. Things worked out. I made them work out. Not perfectly, not without effort, but the gap between wanting and doing was just... small. Small enough that I could step across it without thinking.

Then I became someone else.

It happened gradually, the way these things always do. I got into a relationship in my early thirties that I believed in completely. I was thirty-one, thirty-two, full of hope, ready to build something. And for a while, that's what it felt like, building. But somewhere around thirty-five, thirty-six, something shifted. The person I'd chosen to build with didn't believe in what I was building. Didn't believe in me, really. And here's the thing about being told (quietly, persistently, in a hundred small ways) that you're not quite enough: eventually, you start to agree.

I stopped dreaming the way I used to. Stopped reaching. The gap between wanting and doing didn't just grow, it became the permanent landscape. I lived in it. I built a life inside it. I called it being realistic. I called it being responsible. I called it growing up. What it actually was, was disappearing.

By my late thirties, I was depressed in the clinical sense, the kind where you don't trust your own perception of things, where grey is the only colour, where the medication helps just enough to keep you functional and not quite enough to make you feel like yourself. I was hollowed out in a way that's hard to describe to someone who hasn't experienced it, and probably very easy to recognise for someone who has. I knew, intellectually, that the person I used to be was still in there somewhere. I just couldn't find the door.

Then my ex asked for a divorce.

I'm not going to pretend that was anything other than what it was: painful, disorienting, the kind of loss that makes you question everything you thought you knew about yourself and your judgment and what love is supposed to feel like. It was all of that.

It was also, though I couldn't see this at the time, the door.

My first FIDI was the gym.

I'd been thinking about going for months. Not talking about it: I wasn't the kind of person who announces plans I'm not going to follow through on. Just quietly, in the back of my mind, telling myself: soon. When things stabilise. When I feel better. When.

After the divorce, something cracked open. I decided, and I want to be honest about this, for reasons that were not entirely noble. I was newly single. I was forty-one. I wanted to feel better about what I looked like. It was, if I'm being charitable, a marketing strategy: invest in the product, make it more attractive, get back out there. Shallow? Maybe. But I'll take a shallow reason that gets me moving over a profound reason that keeps me standing still.

I found a gym. I showed up. Not once, every morning. Every morning I had to talk myself into it. The first week, I told myself: just go. The second week: just go again. There were mornings my body said stay in bed and my mind ran through a full inventory of reasons why today could be the exception. And on those mornings I learned to say something to myself that I hadn't said in years.

F*ck it. Do it.

Not loudly or heroically. Quietly, in the dark of early morning, pulling on my shoes when every cell in my body was voting for the duvet. A small declaration. An act of defiance against the version of myself that had spent half a decade learning to be still.

I went. I didn't always perform well. Some sessions I was terrible, wrong energy, wrong headspace, going through the motions. I went anyway. I kept going. And then something happened that I didn't expect: it stopped being a decision. I stopped having to argue myself into it. It became just, what I did in the morning. The version of me that argued with himself about the gym had been replaced, quietly and without announcement, by a version that just went.

From the outside, it probably looked like discipline. From the inside, it felt like getting reacquainted with someone I used to know.

I'm forty-two now.

I'm at a new gym where I don't know anyone, training for a Hyrox competition with a friend who looked at me at dinner one evening and said, you exercise a lot. Let's do this together. I do reformer Pilates. I say yes when my friends call, not because I've been talked into it, not because I forced myself, but because somewhere along the way yes became my default again, the way it was when I was twenty-three and the world felt open.

People who knew me before the marriage, before the years I spent slowly becoming smaller, tell me they see the old me coming back. I find I believe them.

This is not an origin story, exactly. It's a rediscovery story. The capacity for FIDI was always there: I had it in my teens, my twenties, that easy relationship with action and possibility. It didn't go anywhere. It just got buried under years of someone else's disbelief, and then my own. The work since has been excavation.

This book is not a motivational book. I'm not going to tell you to believe in yourself, because you probably already believe in yourself enough, the problem is rarely belief and almost always action. I'm not going to promise that everything works out if you just start, because sometimes it doesn't, and a book that pretends otherwise is lying to you.

What I am going to tell you is what I know from my own life and from watching the people around me: that the gap between the person you are and the person you want to be is, far more often than we admit, not a talent problem and not a timing problem. It's a permission problem.

Not entirely. Sometimes the wall in front of you is real, money you don't have, people who depend on your next decision, a body or a brain that doesn't cooperate the way these books always assume. I'm going to be honest about that the whole way through, because I've watched too many writers wave it away, and I won't insult you by pretending the only thing standing between you and your life is a feeling. But underneath the real walls, more often than not, there's also a permission problem. And the permission is the one part of this you almost always control.

FIDI (f*ck it, do it) is that permission. It's not a mood or a personality type or something that arrives when the circumstances are right. It's a decision. One that can be made by almost anyone, in almost any situation, with any amount of fear still present.

I owe you some honesty before we go a step further, because it shapes everything that follows. When I made my first FIDIs, I had a cushion under me. I had savings that could absorb a couple of bad years. I had no children waiting on the outcome of my choices. I had a passport that let me change countries, and a body that recovered when I pushed it. None of that made the decisions easy, but it made them survivable in a way they simply aren't for everyone. If you're reading this with none of that beneath you, your FIDIs are not smaller than mine. They're braver. The decision is the same. The stakes are not, and I'll show you where the calculus changes rather than pretend it doesn't.

There's one more honesty I owe you, and it matters more than any of the others. When I describe my own grey years, I describe them as someone who was, the whole time, on medication a doctor had prescribed and was actively managing. I had a floor under me that not everyone has, and I know it makes me different. So let me be very clear: if you are in clinical depression as you read this, I am not going to tell you to "just start." I won't tell you to force the small action or FIDI your way out of a condition that is medical, not motivational. "Just open the document" is not advice for someone for whom opening the document is, today, genuinely not possible, and I won't put that pressure on you through these pages.

But I won't leave you with nothing, because there is a FIDI here. It just isn't the gym, or the business, or the leap. For you, right now, the FIDI is the phone call. It's deciding to bring this to your doctor or your therapist, to say it out loud to someone who can actually help, instead of carrying it alone for another month. That decision is action. It is the exact opposite of standing idly by. Choosing to sit down with your medical team and talk about the next step is, in the truest sense this book means the words, a f*ck it, do it, and for a great many people it is the most important one they will ever make. Everything else in here can wait until you've made that one.

And one last piece of honesty, this time about the edges of the book itself. I rebuilt after a particular kind of collapse (divorce, depression, a life gone grey) and I did it without children who depended on me, without a disability or chronic illness to work around, without the wiring of ADHD or a brain that handles starting differently than mine does. Those are not small differences. The single parent, the person whose body won't cooperate, the reader for whom "just start" runs headlong into executive dysfunction that is neurological and not a matter of willpower; they face versions of all this that I have not lived. I'm not going to stand here and narrate experiences that aren't mine. What I can promise is two things: where the framework has to bend for a life unlike mine, I'll say so plainly instead of pretending it doesn't, and I won't ask you to take my word for how that bending works. A few chapters from now you'll reach a chapter built entirely from the true stories of people who have lived these constraints: single parents, people whose bodies or brains don't cooperate, people carrying others. I've changed names and identifying details to protect them, because what they did, and what they did it under, matters more than who they are. That chapter is theirs, not mine, and it's the most important one in the book for anyone whose wall is real.

That same practice extends to other real stories woven through this book. I've changed names and identifying details throughout (I sought these people out, interviewed them, or drew from verified first-person accounts) because what someone did under real constraint matters more than their legal identity. The stories are true. The blur is protecting what they shared.

I know how hard the deciding is, because I had to make it every morning, in the dark, pulling on my shoes.

I'm still making it.

So are you, whether you know it yet or not.

Let's get into it.

A note before we begin: this book has a challenge at the end of every chapter. Think of them as experiments, not assignments, small tests you run on your own life to see what happens, not homework to be graded. Several are just ways of noticing something more clearly. You're free to skip every one of them and the book still works. But the people who got the most from it were usually the ones who tried a few.

Chapter 1: The Gap

I want to tell you about someone I love.

I'm not going to name her. She's my best friend, has been for more than twenty years, and she's still very much in my life, so this isn't a story meant to embarrass. It's a story meant to ache a little, because it should.

She has a gift. A real one. The kind that isn't manufactured by courses or curated by algorithms, the kind that just lives inside someone, fully formed, waiting. She sees light differently than the rest of us. She points a camera at something ordinary (a face, a street corner, a moment between two people) and what comes back is extraordinary. Cinematic. Felt. She can make you feel the weight of a whole story in a single frame.

I've watched her pick up that camera and put it down more times than I can count.

Pick up. A burst of work. Something beautiful. Then, nothing. Life reasserts itself. The kids need something. Work is exhausting. I don't have the time. There's always a reason, and the reasons are always real, and the camera goes back on the shelf.

That's the one I hear most from her: I don't have time. And I understand it, she's busy, genuinely, the way everyone is busy. But I've known her twenty years, and I've watched her find time for plenty of things that matter to her less than this does. The time isn't really the problem. The time is just the most respectable place to put the thing that is.

I used to push. You should be doing this. You're too good to let this sit. The world needs what you make. I'd send the messages. Have the conversations. Watch the flare of excitement (the same one every time, this little fire of yes, you're right, I'm going to do it) and then watch it go out.

I don't push anymore, not because I stopped caring but because she knows. She knows what she's capable of. She knows the camera is there. She knows I'm there. The door is open. The question was never whether she knows what she wants; it's whether she'll ever give herself permission to go get it.

That's the gap.

No dramatic cliff edge, no single moment of cowardice. Just a slow, quiet, daily accumulation of not yet, until one day not yet becomes not really becomes not anymore, and the gift that was there, fully formed, just waiting, never makes it out into the world.

I think about her often. I think about what she'd make if she just said: f*ck it. I'm doing it.

I think we'd all be richer for it.

The word for what lives between intention and action isn't laziness. It isn't lack of ambition. It isn't even fear, though fear is almost always in the room. The word is the gap.

The Space Where Lives Are Lost

The gap is the distance between I will and I did.

It's not dramatic. Nobody marks the day they decided not to write the book. Nobody keeps a record of the morning they woke up and chose, for the four hundred and thirty-seventh time, not to start. The gap doesn't announce itself. It just quietly swallows things: time, energy, ideas, years.

Most people who make New Year's resolutions don't keep them. That should bother you. The figure you'll see quoted is somewhere around ninety percent, and I'll be straight with you, that number gets repeated everywhere without anyone quite being able to point to where it came from, so treat the decimal places with suspicion. But you don't need a precise statistic to know the shape of it is true. You've watched it happen. The gyms that overflow in January and empty by February. The resolutions announced with total certainty and quietly abandoned before the Christmas tree is back in the loft. The intention that was completely real on the first of the month, and gone by the end of it.

These aren't lazy people. Many of them are ambitious, intelligent, driven. They meant what they said on January 1st. The intention was real. The gap just ate it.

And that's just resolutions, the easy ones. The ones with a built-in social ritual and widespread cultural support and the clean slate feeling of a new year. Think about the quieter intentions. The ones that never make it to a list. The ones people carry around for years without saying out loud.

The business idea you've mentioned to no one.

The health change you've been "about to start" since your last birthday.

The thing you know you need to say to someone.

The Gap Shows Up Everywhere

The gap isn't only about careers and creative projects. It's also about the text you didn't send, the friend you kept meaning to call, the invitation you looked at for three days before letting it expire. The gap shows up in relationships with the same mechanics it shows everywhere else: a story about why now isn't the right time, followed by silence that slowly becomes the new normal.

John Gottman, the psychologist who spent decades studying why marriages survive or fail, found something that applies far beyond marriage. He watched couples in conversation and tracked what he called "bids", small attempts at connection, often just a sentence or a gesture. What separated the couples who stayed together from those who divorced was not how they fought or how they celebrated. It was the ratio of bids they turned toward versus bids they ignored. The couples who divorced turned toward each other's bids roughly a third of the time. The couples who thrived turned toward them 86% of the time.

The gap in relationships is missed bids accumulating into silence. You didn't mean to drift from that person. You just kept meaning to reach out, and the meaning to never became the doing. After enough missed bids, the connection atrophies, not from a single dramatic failure, but from a thousand small permissions never granted.

Here's the loneliness trap: almost everyone is waiting for someone else to go first. The person you're thinking of right now is probably not avoiding you; they're caught in the same gap you are, rehearsing the same opening line, convinced on some level that if you really wanted to hear from them, you would have called by now. Both of you are wrong. Both of you are waiting. The gap is a coordination problem dressed up as a shortage of caring.

This matters for everything that follows because the permission problem is not domain-specific. The same mechanism that keeps you from opening the document keeps you from opening the conversation. The story you tell yourself about why you can't start the business is the same story you tell yourself about why you can't renew the friendship. The gap is the gap. The FIDI is the FIDI. And the practice of one, practiced honestly, begins to train the other.

The Paradox of the Prepared

The strange thing about the gap is that the people who live in it are rarely passive. They're not sitting around doing nothing. They are, in fact, extremely busy.

They're researching. Planning. Gathering information. Building systems. Taking courses. Reading books about people who did the thing they want to do. Watching interviews with people who did the thing. Creating spreadsheets, timelines, mood boards. Building the perfect conditions for beginning.

There's a word for this: preparation. And preparation is good. You need some of it.

But at some point, and this is the thing nobody wants to say out loud, preparation becomes a disguise.

It's the most socially acceptable form of procrastination ever invented. Nobody can argue with "I'm still doing research." Nobody can fault you for "wanting to do it right." The person who never starts and the person who's being diligent look identical from the outside. That's part of what makes the gap so comfortable. You can live there indefinitely and still feel like you're moving.

You're not moving. You're parked in a running car.

The Science of Standing Still

Psychologists have a name for the default pull toward inaction. They call it status quo bias, our tendency to maintain the current state of affairs, to treat "doing nothing" as the safe choice.

The research on this is extensive and depressing. In decision after decision, across every domain of life (careers, investments, relationships, health) people systematically choose the familiar over the unfamiliar, the known over the unknown, the existing over the possible. Not because the existing is better. Simply because changing it requires action, and action carries risk, and risk feels like loss.

And here's the cruel neurological fact underneath it all: losses feel approximately twice as powerful as equivalent gains. This is prospect theory, from Daniel Kahneman and Amos Tversky, two of the most important psychologists of the twentieth century. Your brain is wired to feel a $1,000 loss more intensely than a $1,000 gain. To feel the prospect of humiliation more sharply than the prospect of success. To feel what you might lose more acutely than what you might gain.

Which means the gap isn't just psychological laziness. It's the product of a nervous system that evolved over hundreds of thousands of years to treat unfamiliarity as danger. Your brain isn't broken; it's doing exactly what it was designed to do.

The problem is that it was designed for a world that no longer exists. A world where most new things could genuinely kill you.

The thing you want to start probably won't kill you.

It might embarrass you. It might fail. It might cost you money or time or pride. But you'll survive it. Almost certainly better than you'll survive a life of standing in the gap wondering what would have happened if you'd moved.

What the Long View Tells Us

In the 1990s, two Cornell psychologists (Tom Gilovich and Victoria Medvec) did something simple and illuminating. They asked people to reflect on their biggest regrets.

What they found split neatly in two by time frame.

In the short term, people regret their actions more. The embarrassing thing they said. The investment that didn't work out. The relationship they rushed into. You act, it goes wrong, you feel bad.

But in the long term? The pattern reverses, completely and decisively. Over a lifetime, people regret their inactions far more than their actions. The job they didn't take. The person they didn't tell. The thing they didn't build. The life they kept meaning to live.

The study has been replicated across cultures and updated multiple times. The finding holds. In a 2018 paper, Gilovich found that the deepest regrets tend to involve failures to live up to our ideal selves, the person we imagined becoming, rather than failures of behavior. We don't lie awake at sixty-five thinking about the time we tried something and failed. We lie awake thinking about the version of ourselves we never became because we never tried.

That's the gap. Measured across a lifetime.

Enter FIDI

This book is about closing the gap.

Not by being fearless; that's not realistic, and fearlessness is overrated. Fear is often useful information. The thing that scares you usually scares you because it matters.

Not by eliminating uncertainty; that's not possible. The future is not knowable. You will never have all the information. If you're waiting for certainty to act, you're waiting for something that will never arrive.

Not by being more disciplined, more motivated, or more prepared; you probably have enough of all three. What you're missing isn't fuel. You're missing permission.

FIDI (F*ck It, Do It) is that permission.

It's what happens in the moment when the analysis ends and the action begins. It's the breath before you hit send. The step before you've talked yourself out of it again. The commitment made before the doubting voice in your head has a chance to build its case.

FIDI is not a mood, a personality type, or a gift some people have and others don't. It's a decision, one that can be made by almost anyone, in almost any situation, with any amount of fear still present. The fear is the same for everyone. The stakes are not: a FIDI costs more when you have less to fall back on, and I'll keep coming back to that honestly rather than pretend the risk is spread evenly. But the decision itself is always yours to make.

Some people call it courage. Some call it bias for action. Some call it a calculated bet. In startups they call it "shipping." In the military they call it the OODA loop. Philosophers have been writing about it for two thousand years under different names.

I call it FIDI. Because the words matter. The slight irreverence is intentional. "F*ck It" acknowledges the resistance (the fear, the doubt, the very real reasons NOT to act) and chooses to move anyway. The "Do It" is the commitment. Together they are a declaration: I know this isn't perfect. I know it might not work. I'm doing it anyway.

Two Kinds of FIDI

There are two ways the gap opens up in your life.

The first is when something is offered to you. An invitation. An opportunity. A chance to be part of something. And your default, the thing your nervous system does automatically, is to hesitate. To find reasons to say no. Too busy. Too expensive. Too unfamiliar. Too uncomfortable.

This is Passive FIDI. Someone is offering you a door. FIDI means walking through it.

The second is when you've been sitting on something. Your own thing, that you've been carrying, planning, refining, preparing for. The project, the conversation, the leap. You've had it for months, maybe years. You're not waiting for an invitation, you're the one who has to create the moment.

This is Active FIDI. Nobody is going to hand you the start. FIDI means creating it yourself.

Both matter. Both require the same muscle. And in my experience, they feed each other. The person who practices Passive FIDI, who says yes to the small things, builds enough tolerance for uncertainty to eventually take the bigger active leap.

The gap closes the same way in both cases. One decision at a time.

Before We Go Further

One thing needs saying before we spend the rest of this book together.

FIDI is not YOLO.

It isn't "move fast and break things," or recklessness with a philosophical name tag, or an excuse to blow up your life because you read a book that told you to.

There are times when inaction is exactly right. When patience is a virtue, not a cop-out. When more preparation genuinely is the answer. When the cost to others outweighs your desire to act.

We'll get to all of that. There's an entire chapter on when NOT to FIDI, because a philosophy that doesn't have guardrails isn't a philosophy, it's a liability.

But I want to stake the premise clearly, because everything else builds on it: most of the time, the gap you're living in is not protecting you. It's costing you. And the thing you're waiting to become is not going to appear. You're going to have to go get it.

That's what this book is about. Let's close the gap.
