Publicity is absolutely critical. A good PR story is infinitely more effective than a front page ad.

When employees tell you about their good ideas for the business, don't limit your response to asking questions, taking notes and following up. If you can, ask those people to lead their projects and take responsibility for them. From those experiences, they will then have built the confidence to take on more and you can take a further step back.

We spend most of our lives working. So why do so few people have a good time doing it?

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.

Having no regrets makes way for the best piece of advice I can give - don't be afraid of failure.

If family or friends are unwell or ill - it's perhaps the only thing that really can make one feel vulnerable.

Unless you dream, you're not going to achieve anything.
