Motivation, passion, and focus have to come from the top.

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.

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.

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

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.

Best merchants are the ones who dictate cool, not those who try to predict it!

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?'
