What is DIESTRONG?

Updated: July 24, 2026.

DIESTRONG is a philosophy of life for living with strength until your very last breath, and it uses death to sharpen clarity, urgency, and action. Not just physical strength. Mental, spiritual, financial, relational...strength in every aspect of life. It starts in the gym and transfers to every corner of your life, including the people around you.

I originally wrote DIESTRONG for myself. In a lot of ways, it came from long conversations I had with me.

I went back to my hometown in Brazil, Porto Alegre, for a surgery, twenty years after I left for the United States. It was supposed to be two months. It turned into nine due to surgical complications, and this gave me something I don't usually get: real time to think and reflect, longer and deeper, from the place where my journey started. I looked hard at what I want out of the next phase of my life. It started as a manifesto, just me getting clear on what I believe. Then it became principles I try to live by. I'm a visual thinker, so I organized those principles into a framework that made sense to me. At some point I started sharing it with close friends, and they told me, "You need to turn this into something we can use." So I wrote. And I wrote. And eventually, here we are.

This version is different. This one is for you. But I'm not writing as a guru. I'm writing as a practitioner, learning and building this in real time. In some areas I have more reps than others, but I'm not an expert on anything. I never even considered writing a book, much less on such a subject. A philosophy for life?

What is a philosophy for life anyway? And why should we care about it? A philosophy for life is a way of thinking about life that tells you what really matters to you and how to act on it. It's your guide, your bible. Nothing academic about it. And you already have one, whether you chose it or not. If you never sat down and decided what yours is, you absorbed one from your family, your culture, your religion, and the people around you, and it's making your decisions for you right now. Mine is DIESTRONG.

But a philosophy can end up as a collection of inspiring words if you never put it to work and stress test it in life's difficult moments. How do you turn a way of thinking about life into the life you actually want to live? That's where the framework comes in. A framework is a tool for organizing complex ideas into something useful. There are frameworks for software development, business management, law, and healthcare, for almost any subject where you need to understand something, plan it, and execute. Almost none of them covers everything in its subject, especially something as complex as life, so you build a toolbox of frameworks and use them to make sense of things from different angles.

The DIESTRONG philosophy tells you why. The framework tells you how. But it's not intended to be your only framework in life.

I've spent most of my life focused mainly on my own development, and that of the teams and organizations I've been part of. My health, my education, my career, my financial stability. I want to dedicate the next phase to others, to making people stronger. That's the legacy I want to leave. I want DIESTRONG to be part of my legacy, and I think it's important to share where the name came from. DIESTRONG is not short for DIEGO STRONG. It's actually the union of DIE and STRONG, death and strength.

Strength came first.

I was 13 when I first walked into a gym. I was overweight, asthmatic, bullied, and invisible to girls. I just wanted to lose some weight and have a "normal" life. What I got instead was the discovery this whole book is built on: strength transfers. What I built in that gym showed up in how I slept, how I ate, how I studied, and eventually in a flight attendant job at 18 that funded a one-way trip to the United States, a degree I paid for with athletic and academic scholarships and no debt, and a career across finance, entertainment, and technology, from Wall Street to Silicon Valley. None of that happens if I don't walk into that gym at 13, where I first learned that if I could change my body, I could change the trajectory of my life.

Death came later.

I've had my own close calls. I almost died in a serious bicycle accident over twenty-five years ago. During this time I've had five surgeries due to the accident, each with more complications than the previous one: two infections, severe rhabdomyolysis, and anesthesia awareness, where I could hear the doctors joking as they pulled my head back into position and I couldn't move, couldn't speak, couldn't tell anyone I was awake. Two robberies at gunpoint. In one of them the gun went in my mouth and the guy threatened to pull the trigger if I didn't open the door of my house where my family was asleep. That was twenty years ago and I can still taste the metal.

I've also lost the two people who shaped me most. My grandmother died at the dinner table, surrounded by the family she'd spent her whole life holding together. My father died alone, estranged and indebted, by his own hand. The dichotomy of their deaths shaped how I think about life, what we leave behind, and what I choose to build while I'm here. Each of them was strong in their own way, hers in presence, his in drive, and each poured that strength into something that came apart once they weren't there to hold it up. I'll go deeper on both in the Legacy chapter.

All these events got me thinking about my own end and how I wanted to live until that last moment, but I still couldn't put words to what I was actually after. I had the feeling. I didn't have a name for it. Then I saw a t-shirt.

I was in Singapore for work and saw a guy in my hotel wearing DON'T DIE across his chest. We spoke briefly. He was Bryan Johnson. Never heard of him. I looked him up because he was speaking at a longevity event I'd been invited to attend. Tech founder who sold his company and now spends a fortune on a single goal: not dying. Hundreds of biomarkers tracked, a rigidly controlled diet, experimental protocols, aging treated as a disease to be defeated.

I have real respect for what he's doing. He could have retired or started another fintech startup, but he chose to work on what I consider to be the most important thing in life: health. He takes it seriously, he funds his own research, he holds a level of discipline almost nobody sustains, and he refuses to accept decline as inevitable. He's also absorbing an enormous amount of mockery for it, which I have no interest in adding to. He was generous with his time and genuinely kind. And I know what it's like to be the one people laugh at over your own body. I was bullied when I was overweight. I was bullied when I got in shape.

I think our work is complementary. His mission is pushing our lifespan as far as possible, and if that research buys us more years, I'll take them and so will you. My mission is what we do with the years we already have. Both problems are important, but I consider mine more urgent because billions of people aren't doing the basics to have good health right now, and because what I'm building reaches well past health.

That's where the name DIESTRONG came from. I'd been circling this for years without a word for it, and a shirt that said DON'T DIE turned out to be exactly what I needed to see.

People ask me why it's DIE and not GROW STRONG or BUILD STRONG. Either one would be easier to sell. Who wants to wear DIE across their chest as an affirmation? But if you die strong, it means you grew strong, you built strong, you lived strong the whole way there. You can have a stretch of your life where you were strong and then watch it go downhill into the slow, painful decline we all say we want to avoid. The one where the people around you start wondering when you're finally going to go.

I'd rather live with the strength of a lion until 80 than push as far as I can as a weak little cat. The goal isn't to avoid dying. The goal is to arrive at that moment proud of how you lived, what you built, and who you left stronger. One last loud roar, and then move on to the next adventure.

Live fully. Die strong.

The Enemy

Most of what's in this book, you already know. You know you should sleep more and scroll less. You know the conversation you've been avoiding needs to happen. You know which relationship is draining you and which habit is quietly costing you years. Nobody needs another article explaining that vegetables are good or another video explaining how to do squats correctly. The knowing is not the problem. The doing is.

And every so often, life gives you a push on the doing part. A scare. A diagnosis. Somebody's funeral. A birthday with a zero in it. For about a week everything is obvious. You know exactly what matters, exactly what you'd cut, exactly who you'd call. You feel unstoppable.

Then it fades. The urgency gets buried under emails and meetings and the noise of an ordinary week, and a few weeks later nothing has changed.

That's the gap this book exists to close. Clarity is the starting point, but it's useless on its own. What turns clarity into a better life is action. Not running around looking busy. Thoughtful action. That's why you need principles you actually live by, systems that run on your worst day, standards you don't renegotiate every morning.

Without that structure, you drift.

Drift is our enemy. It doesn't announce itself and it doesn't feel like a decision. Drift is the slow settling into a life you didn't design and build deliberately: work that drains you, habits that weaken you, relationships that shrink you, years that pass while you tell yourself the real work starts soon. Nobody drifts on purpose. You just wake up one day further from where you meant to be than you can explain.

And drift doesn't travel alone. It brings company: thinking small, ducking anything that requires courage, choosing the comfortable option every time, and treating the people around you as an afterthought. I have a word for this: Frango. In Brazil, it means chicken, and in the gym it's what you call the guy (or lady, franga) who isn't really training. Going through the motions. Half reps. Phone between sets. Picking the weight they know they can handle. They are there (in fact, they take selfies as proof). They are just not doing the real work.

I'm using frango more broadly because how you show up in the gym is how you show up at home, at school, at work. Everywhere. The gym is one of the few honest rooms left. You can't fake a set, you can't outsource a rep, you can't borrow someone's body to do the work for you. Whatever you do under a barbell when it gets uncomfortable is what you do in the rest of your life when it gets uncomfortable. Watch someone train once and you'll know more about them than ten meetings would tell you. This is why I take anyone I'm thinking about bringing close, in business or in life, to the gym with me first. In the gym, the frango has nowhere to hide.

So frango has nothing to do with how big or strong you are. You can be the biggest guy in the room and still be a frango. It's not about your body. It's about how you think. Your behavior. Frango is not about being small. It's about thinking small. Excuses over effort. Too busy to sleep. No time to train. Too old to start. Too young to worry.

Frango represents everything this framework was built to fight. Where DIESTRONG says choose your identity, the frango accepts whatever he was handed. Where it says hold the standard, the frango negotiates it down. Where it says build the people around you, the frango can't be bothered to build himself.

Everybody acts a little frango sometimes, myself included. This is why I wrote DIESTRONG for me first. It's also why I was the first to wear DON'T BE A FRANGO across my chest, and I still wear it every day.

Everywhere I go, I get compliments on the shirt. And when I tell people what's behind it, they love it even more. Then I ask them: do you want one? Are you willing to wear it and face yourself in the mirror every day?

How about you?

What You Get

DIESTRONG is for anyone who wants to fight the frango inside them.

If that's you, here's what you'll learn to build: your own version of DIESTRONG, layer by layer. But I'm not giving you the answers. I'm giving you the structure to build your own life philosophy and framework, and recommended actions to build your life with them, based on the following areas:

Foundation builds your capacity to execute. A body that performs, a mind that governs itself under stress, and a spirit that holds when outcomes turn against you. This is where every principle in the book is learned first, physically, before it gets applied anywhere else.

Compass helps you define who you are and where to aim. The identity you chose instead of the one you inherited, the values you'll hold no matter what, and the mission that decides where your finite hours go.

Arenas are where you show up and contribute: Family, Work, and Citizenship. This is where the internal work becomes visible to other people and impacts their lives.

Legacy is what keeps building after you move on. You'll write a Legacy Statement that declares what you'll make true, and a Legacy Plan that turns it into actions on your calendar this week.

None of that stays theoretical. The framework runs 3 layers, 9 pillars, 27 practices, and 81 principles. Every principle comes with three actions I picked because they make the biggest difference if you do nothing else. That's 243 actions, and the book will eventually have many more. Every practice also comes with a self-assessment so you know where you actually stand, and a Make It Real section that turns the reading into something written down and scheduled. You'll go through that 27 times. By the end you'll have your own version of DIESTRONG, in your own words, built for the life you want to live now and be remembered for.

You'll stop drifting. You'll start building with purpose. You'll live with strength, until the very end. That's what it means to build, live, and die strong.

You're reading a beta version of this book. I'm publishing it here in pieces, one layer every two weeks or so, while I'm still writing and editing it. That means you're getting it early and rough, and it means your feedback actually shapes what this book eventually becomes. If something lands, tell me. Let's build this together.

Read the DIESTRONG Manifesto (out loud, make me proud!).

Then start with the DIESTRONG Framework. Here's where we turn the philosophy into action.
