It takes a lot of things to work together in order to be wealthy but with a little luck, a lot of luck... You've got to be good at something. For a 20-year-old, you don't have to know exactly what you want to do, you've just got to go find something you can be great at, and then go be great at it.
Mark CubanIt doesn't matter how many times you fail. It doesn't matter how many times you almost get it right. No-one is going to know or care about your failures, and neither should you. All you have to do is learn from them and those around you. All that matters in business is that you get it right once. Then everyone can tell you how lucky you are.
