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.

The sports apparel industry was dominated by the big shoe companies. But there was a void in apparel and I decided to fill it.

Any self-respecting entrepreneur has borrowed money from their mother at some point.

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.

As foreign as it would be for you to go running in regular shoes, I want it to be just as foreign for you not to work out in your Under Armour.

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.

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.
