Give your employees a mission that matches their ambitions. When you challenge people, they surprise you.

Kitesurfing is one of the greatest sports in the world. I highly recommend this to anyone who has access to the ocean. There is nothing more freeing than being out there and kitesurfing.

The entrepreneurs who succeed usually want to make a difference to people’s lives, not just their own bank balances.
