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.

The best advice I ever received? Simple: Have no regrets.

I know enough to know that no man is an island.

You can create a business, choose a name, but unless people know about it you're not going to sell any products.

In the '80's my gut feeling was that airlines were crap. I hated spending time on planes. I thought we could create the kind of airline I'd like. So we got a secondhand 747 and gave it a go.

A successful business must have a sound knowledge of its market and work on how its product or service will be different, stand out and improve people's lives. If you can ensure it responds to a real need in the market place, your business can punch well above its weight.

Success cannot be measured in wealth, fame or power, but by whether you have made a positive difference for others.
