You can't do a good business with a bad person. Find the right people to work with and you can't go wrong.

Giving back has to do with the way I was brought up and the fact that I've traveled widely and seen terrible situations in the world. To sleep well at night, those of us who are in a position to help must address these situations. I'd get far greater satisfaction out of, say, walking into a hospital I'd built in South Africa than I would by sitting on a beach. I'm fortunate enough to be in a position to make a difference, and I don't want to waste that. I suspect I was also lucky to have parents who drove me from a young age.

If you can run one business well, you can run any business well.

Whether your sport of choice is running, cycling, kite surfing, etc. start moving and stay moving! It will give you energy and help you stay young.
