Introduction

I'm somewhere on the seventh floor of a fifteen-floor building.

The stairwell smells like fresh concrete. Half a dozen plastic bags are hanging off my arms - groceries, bottles of water, a stack of diapers - and the handles are cutting into my hands. I'm breathing hard, and the sound fills the stairwell. Three more flights to go.

Somewhere above me, on the tenth floor, my newborn twins are waiting.

This was Moldova, where my wife is from. We had just moved into a newly built apartment. The building looked great from the outside. The catch was that the developer had run into trouble with the law and fled the country, leaving the place unfinished. The elevators didn't work. They wouldn't work for a long time.

So every grocery run became a stair workout with bags. Every walk with the babies meant carrying them down ten floors and back up again. Every trip outside was a small expedition.

I stop on the seventh-floor landing, set the bags down, and listen to my own breathing. And I think - almost to myself, almost out loud:

Something has to change.

I stand there a while, longer than I need to.

And then, a wider thought. A lot of people I know are standing in some version of the same stairwell, tired in a way sleep doesn't fix, going through the motions of a life that was supposed to feel different. The life we'd been handed had bugs in it.

The stairs weren't really the problem. The stairs were just the last weight on a load that had been building for quite a while.

It was 2015. I was 35 years old. My twins had just been born. I had just started a company called Zeroqode.And I was on the brink of a real emotional and physical breakdown, though I didn't yet have that language for it.

We had the apartment in Moldova, but staying there long-term wasn't really possible. When the twins were three months old, we packed up and left for Spain. That became the pattern. A few months in one place, then we'd have to leave again. Spain. The UAE. Back to Moldova. Somewhere new.

We weren't traveling for fun. We were trying to find a way that life with two newborns wouldn't crush us.

My marriage was under enormous strain - which often happens when two exhausted people have nothing left to give each other.

If you'd asked me back then what I was doing, I would have told you the truth: I was just trying to keep everything from falling apart.

A new business takes every ounce of energy you've got. Newborn twins take every ounce that's left. There's nothing in the budget for the rest. My wife carried most of the load with the babies - she was the main caretaker, and I still don't know how she did it. But twins aren't twice as hard as one baby. It feels three times harder. So I was up at night too, helping with feedings, diapers, rocking babies back to sleep - and then trying, a few hours later, to be sharp enough to run a company.

So I started experimenting. Not because I wanted to optimize my life. Because I was running out of options.

I tried things one by one. Whatever I could find. Whatever I could afford. Since we were always on the move and money was tight, anything I tried had to pass two simple tests: it had to be affordable, and it had to work wherever I was. No expensive gadgets. No fancy clinics. Nothing that needed me to be in one place for long.

That's how this quest began.

What I didn't expect was where it led.

The modern world is full of more. More pills. More supplements. More treatments. More gadgets. More apps. More programs. More products. Everywhere you look, someone is telling you the answer is to add one more thing.

What I kept finding was almost the opposite.

The techniques that actually worked - that genuinely changed how I slept, how I felt, how I worked, how I showed up for my family - were almost always about doing less, not more. Removing instead of adding. Simplifying instead of stacking. Using what was already within reach: my breath, my body, my time, the sun, water, sleep, silence, the people around me.

This book is built on that idea.

What you're about to read is what I've collected since. Various experiments and techniques - some small, some bigger, some conventional, some exotic. Things that sounded ridiculous until they worked. Some are ancient - practices people have known about for thousands of years and since forgotten. Some are modern - things only really understood in the last few decades.

I tried to make this book holistic. It covers physical and mental well-being, productivity, personal growth, money and success, relationships, parenting, and the daily rhythms that shape a life - pretty much every area where I've found something that genuinely makes a difference.

The point of putting it all in one place was simple: I wanted to save you the quest. I read everything I could get my hands on, old and new. I tried things on myself, sometimes for years. What's in here is what survived. It's distilled from real experience, not theory.

It started in desperation. It turned into a way of life.

Most of it costs almost nothing. Most of it you can start today, wherever you are.

More than anything, this handbook is built to help you:

You don't have to read this book front to back, though you can - it's organized into a path that makes sense - but you can also flip through the table of contents and follow whatever pulls you in. Drawn to sleep? Go there. Curious about cold therapy? Start with that. Looking for help with a specific issue? Chapter 6 is built for exactly that. This book is meant to be a companion you can dip into, not a curriculum you have to complete.

A note on density. There's no fluff in this book. Almost every page is new ground, and I haven't padded any topic to make the book feel weightier than it needs to be. I've also kept the scientific apparatus to a minimum. You won't find me walking you through every study's methodology, sample size, control group, or statistical significance. You'll get the bottom line: what works, why it works in plain language, and what to actually do about it. If you want the deeper scientific weeds on any specific topic, the recommended readings throughout the book will take you there. The aim here is the practical distillation: maximum useful information in minimum reading time.

This book itself is a living thing. It reflects what I've found so far and will change as I keep learning. Some of what's in here will sound strange or unconventional - come to these pages with an open mind. Most of what I trust now started as something I would have dismissed if I hadn't been desperate enough to try. Try things first. If they don't match your experience, hold them loosely. Take what's useful. Leave the rest.

One more thing before you go in.

I'm not a guru. I'm not perfect. And I'm not a subject matter expert in anything I talk about in this book. Moreover, I don't follow every piece of advice in this book religiously - nobody could, and nobody should. On any given week, I'm solid on some of this, hit-or-miss on others, and a few things I've let slide.

What I do try to keep doing is stay tuned in - to my body, and to my mind. I pay attention to my sensations, my feelings, my energy, the small signals that come up across a day. Some days my body wants the sauna; some days it doesn't. Some weeks fasting feels easy; some weeks it doesn't. Some mornings my mind is ready to do the work; some mornings it needs a small nudge to get there. I let all of that guide me.

I notice what feels possible right now, what feels like a stretch worth taking, and what feels like my body or my psyche pushing back. When something pushes back, I don't try to bulldoze through it. But I don't always back off either. I take it as information, then I decide.

Because the real game here is a balance - a dance, a push and pull, between two failure modes.

On one side: brute force. You can't bully your body or your mind into a new shape. The harder you push, the more resistance comes up, and the more likely you are to bounce off after a week or two. The willpower-over-everything model doesn't hold up.

On the other side: pure surrender. "Just go with whatever you feel" is its own trap - left entirely to our impulses, we'd skip the cold shower, dodge the fast, sleep past nine, and avoid whatever harder thing the day called for. Sometimes you do need to lean in, gently, past the first "no" - both for the body and for the mind.

The right way through is somewhere in between. Gentleness, patience, attention - and then, sometimes, a small deliberate push. Sensitive enough to know when to back off, firm enough to know when to lean in. It's a feel, not a formula.

Holding hands, in other words - with yourself, with your body, with your mind.
