Have passion for what you do; believe in yourself and your product and your customer; persevere; delegate; listen. Have fun. Today, I add: "Do good".

Branding is everything. A young girl once came up to me and told me I could be famous because I looked just like Richard Branson!

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.

Unless you dream, you're not going to achieve anything.

A generation ago, the image was that you had to trample everyone else down to succeed; but I don't believe that makes good business sense.

I was a risk-taker as a young man, and I don't regret it. I'm not adventurous in quite the same way now, but I still love the challenge of testing myself to the limits, flying around the world, or seeing if I can be the first to fly a balloon across the Atlantic, or trying to take people into space at an affordable price in an environmentally friendly way. I'll be going into space with three generations of my family!
