Mark Cuban's Top 5 Rules to get success in business

1. "Don't start a company unless it's an obsession and something you love. If you have an exit strategy, it's not an obsession."
2. What I've learned in these 11 years is you just got to stay focused and believe in yourself and trust your own ability and judgment.
3. Because if you're prepared and you know what it takes, it's not a risk. You just have to figure out how to get there. There is always a way to get there.
4. "Work like there is someone working 24 hours a day to take it all away from you."
5. What I've learned is that if you really want to be successful at something, you'll find that you put the time in. You won't just ask somebody if it's a good idea, you'll go figure out if it's a good idea.
