I was dyslexic, I had no understanding of schoolwork whatsoever. I certainly would have failed IQ tests. And it was one of the reasons I left school when I was 15 years old. And if I - if I'm not interested in something, I don't grasp it.

I've been taught not to have any regrets. If we were to add up all of the hours spent regretting mistakes and use that time to develop new ideas, who knows how many brilliant new businesses would be created.

I was trouble - and always in trouble. Aged eight I still couldn't read. In fact, I was dyslexic and short-sighted. Despite sitting at the front of the class, I couldn't read the blackboard. Only after a couple of terms did anyone think to have my eyes tested. Even when I could see, the letters and numbers made no sense at all.

I think sometimes when you come from a conservative background, you want to rebel a little bit. I dropped out of school at 15 and learned early in life that saying yes was a lot more fun than saying no. If you have the opportunity to explore the skies and attempt something people haven't done before - well, I was damned if I was going to sit around watching television while someone else was doing it.

Being dyslexic can actually help in the outside world. I see some things clearer than other people do because I have to simplify things to help me and that has helped others.

Never go into business purely to make money. If that's the motive you're better off doing nothing.

I have enjoyed life a lot more by saying "yes" than by sayings "no".
