Mark Cuban is awesome. He sounded off at the TechCrunch conference about his businesses and what it takes to be successful.

Best lines are the very last paragraph. All about the will to win and a “no excuses” philosophy about knowing your business cold.

JC: Whats the best piece of advice you can give a young entrepreneur?

MC: Ill tell you what I learned from Bobby Knight: everybody’s got the will to win but when it comes time to doing something, it’s always about someone else. Not many people have the will to prepare. You got to be willing to know your product and environment better than anybody. No matter what you do there is someone out there trying to kick your ass. You got to be the smartest guy in the room about your product. Then you need to have a revenue source. You need a company with a revenue to make money. Concept, competition, and where the money is — plus something you love doing. I’ve never had a day of work. When I die I want to come back as me.
