I can't say it enough that learning how to learn is one of the greatest skills anyone can have. It's why I advocate that everyone go to college.

I love being challenged and defending my positions and, when I'm wrong, learning from the exchange. It makes me smarter and better as a businessperson.

Being rich is a good thing. Not just in the obvious sense of benefitting you and your family, but in the broader sense. Profits are not a zero sum game. The more you make, the more of a financial impact you can have.

If there was a template for success in sports, everyone would follow it. You do the best you can and trust the people you trust.

Owning a popular sports team is very different than any other type of business. They don't throw parades when Apple has the biggest quarter in corporate history. People don't call and email asking for anyone from the team to come visit their sick child. They don't cry as they request a jersey of their child's favorite player to be buried with them.

If you can't admit a failure, you're not an entrepreneur. You are not a good business person. There's nothing brilliant about what you are doing.

Culture is very important to the Mavs. Your best player has to be a fit for what you want the culture of the team to be. He has to be someone who leads by example. Someone who sets the tone in the locker room and on the court. It isn't about who talks the most or the loudest. It is about the demeanor and attitude he brings.

I still work hard to know my business. I'm continuously looking for ways to improve all my companies, and I'm always selling. Always.

I love to compete. To me, business is the ultimate sport. It's always on. There is always someone trying to beat me.

Sweat equity is the most valuable equity there is. Know your business and industry better than anyone else in the world. Love what you do or don't do it.
