It's exciting to see how fast your kids learn and grow. I'm not too worried about them, particularly the ones who like to break rules and don't follow instructions; those are the ones that will do just fine because they know what's important to them.

People ask me all the time, 'How can I become a successful entrepreneur?' And I have to be honest: It's one of my least favorite questions, because if you're waiting for someone else's advice to become an entrepreneur, chances are you're not one.

If you have to go through life being unhappy to conform to society around you, that's not a very good deal.
