However small a company, its founders should try to expand people's opportunities and choices.

I never set out to be a businessman

Be swift to take advantage of business opportunities. Bigger companies are too cumbersome to move quickly; this can be a competitive advantage for you.

There are no quick wins in business - it takes years to become an overnight success.

Every great movement in the world starts with a tiny group of people who simply refuse to accept a situation.

And you know, I've had great fun turning quite a lot of different industries on their head and making sure those industries will never be the same again, because Virgin went in and took them on.

When I started Virgin from a basement in west London, there was no great plan or strategy. I didn't set out to build a business empire ... For me, building a business is all about doing something to be proud of, bringing talented people together and creating something that's going to make a real difference to other people's lives.
