Marc Cuban interviewed for the Freakonomics blog:
Question: What advice do you have for a college graduate like myself who is looking to be successful in the business world?
Marc Cuban: It doesn’t matter how many times you fail; you only have to find the one thing you love to do and be great at it. No matter how long it takes. Now is the time to take chances. Live like a student for as long as you can, stay debt-free and do all you can to have a blast.
Question: What is the one thing that you personally believe is the true secret to success?
Marc Cuban: Find what you love to do and be the best you can be at it. Simple, right???
Simple… or simplistic??… I like the advice above (in bold), though.
