My biggest motivation? Just to keep challenging myself. I see life almost like one long University education that I never had - everyday I'm learning something new.

I can honestly say that I have never gone into any business purely to make money. If that is the sole motive then I believe you are better off not doing it. A business has to be involving, it has to be fun, and it has to exercise your creative instincts.

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.

I think entrepreneurship is our natural state--a big adult word that probably boils down to something much more obvious like playfulness.

At the end, entrepreneurship is not about wearing expensive suits and earning a lot of money. It is all about being true to yourself, to your values in life. Your dreams.

Create the kind of workplace and company culture that will attract great talent. If you hire brilliant people, they will make work feel more like play.

Sometimes the riskiest decision you can make is to do nothing.
