Fun is at the core of the way I like to do business and it has been key to everything I've done from the outset.

My number one rule in business, and in life, is to enjoy what you do. Running a business involves long hours and hard decisions; if you don't have the passion to keep you going, your business will more than likely fail. If you don't enjoy what you are doing, then you shouldn't be doing it.

If people are crazy enough to dare, impossible things happen.

You see, it's essential that one of us stays awake during the flight [ballon]. So, rather than using the comfortable Virgin seats which we used to cross the Atlantic, we've asked British Airways for two of theirs.

Doing good is good for business.

In a sense, when we started Virgin Atlantic, I was trying to create an airline for myself. If you try to build the perfect airline for yourself, it will be appreciated by others.

If something can't be explained on the back of an envelope, it's rubbish.
