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.

Great brands are like great stories. And every story has a beginning, a middle, and an end. And our job is to make sure that every chapter of our stories makes sense to the one in front of it and make sense to the one after it. There is no such thing as an overnight success. You have to get up and put your work boots on every single day.

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.

I was a general business major, which meant that in any business school and particularly at Smith School, which is a very good school, you do a lot of team projects. Well I was the guy who gave the presentations for the team projects.

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.

When you see most companies get big, they want to shout about all they've done. But the consumer wants to know: 'What have you done for me lately?'

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.

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.

I'm a big advocate of the power of positive thinking, particularly for small businesses.

We need to stop making wide-body seats on airplanes, stop accommodating that, because it's not healthy.

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.

It's a fire, it's a passion to get out and to create and to innovate. And that I've always enjoyed and I've always been very proud of is that the people I've done business with, the people around me have always made money.

Where can we take no the product, but the idea?

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.
