Have a positive attitude and spread it around, never let yourself be a victim, and for goodness' sake - have fun.

As an investor-entrepreneur, I've always tried to be contrarian, to go against the crowd, to identify opportunities in places where people are not looking.

My biggest motivation… Just to keep challenging myself. I see life almost like one long University education that I never had - every day I'm learning something new, remember that there's always something to be learned, no matter how old you are or how many degrees you have.

You have to be constantly reinventing yourself and investing in the future.

Free enterprise cannot be justified as being good for business. It can be justified only as being good for society.

I think it is often easier to make progress on mega-ambitious dreams. Since no one else is crazy enough to do it, you have little competition. In fact, there are so few people this crazy that I feel like I know them all by first name.
