My love of horses began in College Park, with me and 10 friends on two couches and a keg of beer in the back of a truck, heading to Pimlico at 6 A.M. to mark our place in the middle of the Preakness infield, where we never saw a horse run.

I realized early on that I was pretty good at organizing. A lot of it was about control. While my friends were out getting hammered at concerts, I was making money. I am a control freak.

There's an entrepreneur right now, scared to death, making excuses, saying, 'It's not the right time just yet.' There's no such thing as a good time. I started an apparel-manufacturing business in the tech-boom years. I mean, come on. Get out of your garage and go take a chance, and start your business.

All we're trying to do is change how people think about fitness. And build Under Armour into the biggest brand in the entire land.

One of our first customers asked me how big we want to be. I said I want to be really big. Later, it bothered me that I answered that way. Now I say I just want to be a great company.

My first real business was bootlegging T-shirts - I was just a dumb kid. You go to a concert and pay $25 for a cotton T-shirt that says 'Rolling Stones,' 'Lollapalooza,' or whatever. On the outside they're 10 or 15 bucks. We were the guys selling them for 10 or 15 bucks.

I wake up in the morning and I think about one brand. I don't have enough time to wake up twice and think about two.
