Remain focused on fulfilling your business mission. Never allow adversity divert your attention and efforts.

Perhaps, therefore, it is odd that if there is any one phrase that is guaranteed to set me off it's when someone says to me, 'OK, fine. You're the boss!' What irks me is that in 90% of such instances what that person is really saying is, 'OK, then, I don't agree with you, but I'll roll over and do it because you're telling me to. But if it doesn't work out I'll be the first to remind everyone that it wasn't my idea.'

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.

If I'm setting up a new business I'll spend three or four months learning everything there is about that business, everything there is about that subject and then I will find good people to run it on a day-to-day basis, but whilst they're running it at least I know what they're talking about when they come back to me.

I think great businessmen are more likely made than born. I don't know if it's from your upbringing, your parental background, the struggles you go through. In my own particular situation, I left school at 15 and I was struggling to survive in the jungle and that was a great education. So I think just getting out there, hands on, learning to survive teaches you a lot.

If somebody offers you an amazing opportunity but you are not sure you can do it, say yes-then learn how to do it later!

People have to decide on priorities if they want to get anywhere. The best lessons I learned was to just do it.
