A tendency to focus on art over business has meant that too many designers have failed to make the most of their critical acclaim.

One of my goals is that, at a dinner party some time in the future, someone will say, 'Oh, my nephew is starting a ready-to-wear brand', and 20 people will turn around and say, 'Is he? Can we invest?' in the same way that, now, if you were to say, 'My nephew is starting a mobile app,' everyone would say, 'Oh, smashing! Can I invest?'

You cannot underestimate the impact the Internet has had on British fashion.

You can no longer just have a magazine that shows you this glossy impervious image of women - in the studio, artificial, wearing a push-up bra.

At 25, I made many companies. I was thinking more like a businessman or entrepreneur than a CEO. I created many companies, small companies, medium companies. I tried to be involved in many kinds of activities, in finance, in real estate, in mining.

I won't have to do any major changes to continue my career a long way, hopefully. Just hopefully stay healthy and be able to help a team out as I go through and still play at a pretty high level.

I've had a very interesting career. I get to do amazing things and work with amazing people and travel and learn languages - things most people don't get the opportunity to do.

I was critical of race-based affirmative action early on in my career and I've changed my mind. And I've publicly acknowledged that I was wrong.
