Take a chance - it's the best way to test yourself, have fund and push boundaries.

I'm a lad of the '60s. I started a magazine to try and end the Vietnam war, but it was a number of years before I had the profile, the financial resources and the time to do more.

Avoid litigations. They are expensive and consume loads of time but if you have got a good case and a better chance of winning; then fight it out.

And obviously, from our own personal point of view, the principal challenge is a personal challenge.

I definitely go on gut instinct but it has always had the back up of research and information.

I never really felt secure until I was well into my 30s, because anytime I had success, I would invest in new projects.

There's no better satisfaction than watching the people around you, who have worked day and night to get something right, realising the dream.
