Built to Last: Startup Advice That Won’t Break Your Spirit

Respect the Fundamentals

I’ve been in this gym for twenty-five years. I’ve seen kids come in here with fancy, expensive gloves and brand-new boots, thinking the gear makes the fighter. They spend an hour on the speed bag, look at their reflection, and think they’re ready for the Golden Gloves. Then, I put them in the ring with a guy who’s been training in holes in his shoes for three years, and they get humbled in thirty seconds.

Starting a business is the same thing. Everyone wants the shiny website, the office in the nice part of town, or the fancy logo. But if your foundation is garbage, you’re just decorating a sinking ship. Before you worry about your Series A funding or your marketing aesthetic, ask yourself: do you have a product that actually helps someone? Can you articulate the value you provide without using corporate buzzwords? If you can’t explain your business to a kid from Boyle Heights while we’re wrapping hands, you don’t understand it well enough yet.

The Stoic’s Approach to Burnout

I keep a worn-out copy of Marcus Aurelius on my desk. 'Waste no more time arguing what a good man should be. Be one.'

When you’re starting out, you’re going to get hit. You’ll have a client back out, a supplier fail you, or a month where the bank account looks thinner than a lightweight fighter trying to make weight. Most people panic. They start firing off emails at 3:00 AM, making bad decisions because they’re scared.

In the gym, when a kid gets hit, his gut reaction is to flail or freeze. I tell them: breathe. Keep your guard up. Assess the damage, but don’t lose your composure. If you lose your head, you lose the fight. When your startup hits a wall—and it will—don’t look for someone to blame. Focus on what is in your control. You can’t control the market, but you can control your output, your integrity, and how you treat the people helping you build this thing.

Don’t Build a Glass Jaw Business

I had a hand injury back in the day that kept me from going pro. It hurt, it pissed me off, and for a long time, I thought that was the end of the world. But that injury forced me to become a coach. It forced me to learn the game from the outside looking in.

When you’re building your startup, you need to build in redundancy. Don’t bet your entire company on one client or one specific strategy. If you’re a solopreneur, make sure you have systems that work even when you’re sick or exhausted. I see young entrepreneurs burn out because they think they have to be the hero 24/7. That’s not leadership; that’s a ego-trip that leads to a crash. Build a business that can take a punch. If you’re the only person who knows how to open the door, you don’t have a company—you have a job you can’t quit. Document your processes, build a support network, and stop trying to carry the whole gym on your shoulders.

The Discipline of the Daily Grind

Everyone loves the highlight reel. They love the idea of the exit, the big sale, the glory. But nobody talks about the Tuesday morning when you’re tired, it’s raining, and nobody signed up for your service.

Startup success isn't about the one big idea; it’s about the boring, repetitive work you do when you don't feel like doing it. It’s the follow-up emails, the accounting, the cleaning of the floor. Character is built in the mundane. If you can’t find satisfaction in the work itself, you’re going to quit long before you get to the pay-off. I still sweep the mats in my gym every night. It keeps me humble, and it reminds me that this place exists because I show up, every single day, no matter what.

Find Your Corner

I wouldn’t be here if Rudy hadn’t grabbed me by the back of the neck when I was seventeen and told me I had potential. You think you’re a lone wolf? Think again. You need a mentor, a peer group that will tell you when you’re being an idiot, and a support system that knows the difference between a bad day and a bad business model.

Don’t try to do this alone. Find someone who has 'been through it all'—someone who isn’t just chasing the latest trend but understands the weight of responsibility. If you’re doing this just for the money, you’ll fold the first time you get pressed against the ropes. If you’re doing this because you want to build something that lasts, something that matters to your community or your craft, then you’ve got a fighting chance.

Keep your hands up, keep your eyes open, and don't let the noise distract you from the fundamentals. It’s a long road, but it’s worth the walk.

If you’re feeling like you’re taking too many shots and not enough ground, let’s talk. My inbox is open, and I’ve got plenty of stories—and coffee—to share. Reach out, let me know where you're at in your training.
