I don't live my life thinking about "if only." I just try to think positively about the future. We'll never know for certain what would have happened if we'd gone to Iraq. The important thing is that we've got to do everything we can to prevent other wars.

When I was 15, I left school to start a magazine, and it became a success because I wouldn't take no for an answer. I remember banging on James Baldwin's door to ask for an interview when he came to England. Then I got Jean-Paul Sartre's home phone number and asked him to contribute. If I'd been 30, he might have said no, but I was a 15-year-old with passion and he was charmed. Making money was always just a side product of having a good time and creating things nobody'd seen before.

Please don’t get hung up on this question of whether you need to have experience in an industry before you launch your startup.

As much as you need a strong personality to build a business from scratch, you also must understand the art of delegation.

It's never easy to set up any business, but it comes back to determination and drive and the love of what you do!

Please be polite. Nothing in life should erode the habit of saying thank you to people or praising them.

Engage your emotions at work. Your instincts and emotions are there to help you.
