When I started Virgin from a basement in west London, there was no great plan or strategy. I didn't set out to build a business empire ...

No matter where my travels take me, my day starts with a good work out, preferably kitesurfing or tennis. Exercise puts me in the right state of mind for the day. Dedicating time in the morning to exercise your body will make a big difference when you have to focus your mind on the day's work.

All good leaders listen to their people and empower them to go away and turn any innovative ideas they have into a reality.

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.

Take a chance - it's the best way to test yourself, have fund and push boundaries.
