If family or friends are unwell or ill - it's perhaps the only thing that really can make one feel vulnerable.

The bigger the dream, the greater the opportunity

Look, if you can indulge in your passion, life will be far more interesting than if you're just working. You'll work harder at it, and you'll know more about it. But first you must go out and educate yourself on whatever it is that you've decided to do - know more about kite-surfing than anyone else. That's where the work comes in. But if you're doing things you're passionate about, that will come naturally.

By working hard, by making the right moves, you can create your own luck, I think. But certainly luck plays a part.

Remember the to-do list but don't forget the to-be list.

I have no secret. There are no rules to follow in business. I just work hard and, as I always have done, believe I can do it. Most of all, though, I try to have fun.

Create the kind of workplace and company culture that will attract great talent. If you hire brilliant people, they will make work feel more like play.
