I do a lot of TV stuff, but I also turn a lot down - it's got to be an adventure.

I turn my negatives into my positives because one of my mottos is, 'Yesterday's history, tomorrow's a mystery,' meaning that you can't go back and change anything in the past.

I'm the kind of guy who really likes a challenge. It's more rewarding.

Show me a smile, and I'll show you one back.

Laughter is binary: It either happens or it doesn't. As each joke arrives in the course of a film, the cavernous space of the theater is either filled with joy and laughter or with the quiet of cringing embarrassment. Every time you step to the plate to make a joke, you're going to experience one or the other.

To make others less happy is a crime. To make ourselves unhappy is where all crime starts. We must try to contribute joy to the world. That is true no matter what our problems, our health, our circumstances. We must try. I didn't always know this, and am happy I lived long enough to find it out.

I've never gone into business to make money. Every Virgin product and service has been made into a reality to make a positive difference in people's lives. And by focusing on the happiness of our customers, we have been able to build a successful group of companies.

Start your diet during a period of optimism and happiness.
