Most entrepreneurs will admit luck plays a part in success.

The idea that business is strictly a numbers affair has always struck me as preposterous. For one thing, I've never been particularly good at numbers, but I think I've done a reasonable job with feelings. And I'm convinced that it is feelings - and feelings alone - that account for the success of the Virgin brand in all of its myriad forms.

If you don’t enjoy it, don’t do it. You must love what you do.

If you run a business, put on top your employees, then your consumers, and then your shareholders.

My parents brought me up with this philosophy. You must do things. You mustn't watch what other people are doing. You must not listen to what other people are doing.

All you have in life is your reputation: you may be very rich, but if you lose your good name, then you'll never be happy. The thought will always lurk at the back of your mind that people don't trust you.

I think business leaders all over the world should not just think of how we can make lots of money, which is fine, but to take some of the problems in the world and get out there and tackle them using business. I think that if businesses do that we can get on top of these problems.
