I have learnt so much over my 40 years of business which would have been valuable to me when I was younger.

Business leaders take things far too seriously, and forget that most of the time people spend in their lives is at work, and it should be fun.

People who think and say we more often than I are a lot more likely to succeed.

We will be producing supersonic planes which will go far, far faster than Concordes. New York to Tokyo could be less than an hour. You could be traveling at 19,000 miles an hour orbitally.

So I became a publisher by mistake - well, not quite by mistake, because I wanted to be an editor but I had to make sure the magazine would survive. The point is this: Most businesses fail, so if you're going to succeed, it has to be about more than making money.

Although my spelling is still sometimes poor, I have managed to overcome the worst of my difficulties through training myself to concentrate.

It's really important to find an hour or two to a day to make sure that you keep healthy, keep fit. It's very easy just to forget that aspect. And if you're feeling really good and fit, I think you can get two or three extra hours a day of hard work in as well.
