One of the best bits of advice I can give is, early on, when you're building a new business, try to find somebody to run it on a day-to-day basis to free yourself up to look at the bigger picture.

As we drifted to earth I sat up on the glass roof of the capsule, watching the beauty of the golden dawn as it broke over the desert. This was a day I never thought I'd see and the rising sun and growing warmth of the day seemed very precious. It made me aware that hard-won things are more valuable than those that come too easily. It reminded me to always enjoy the moment.

I may be a businessman in that I set up and run companies for profit, but when I try to plan ahead and dream up new products and new companies, I'm an idealist.

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

Failing can provide invaluable lessons and making mistakes and experiencing setbacks is part of the DNA of every successful entrepreneur.

Enjoy life - you only get one.

Choose great people and shine in their shadows
