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 CubanNever follow your dreams. Follow your effort. It's not about what you can dream of. That's easy. It's about whether or not it's important enough to you to do the work to be ready to be successful in that business.
Mark CubanIt's not whether the glass is half empty or half full, it's who is pouring the water. The key in business and success at any endeavor is doing your best to control your destiny. You can't always do it, but you have to take every opportunity you can to be as prepared as-and ahead of-the competition as you possibly can be.
