I just love every minute of my life. I love the variety. Every minute of every day I'm meeting fascinating new people, learning and working with wonderful teams of people creating wonderful things.

I learnt from an early age this need to delegate responsibility out to other team members as there is just too much for one person to do themselves. What is the point of hiring talented team members if you don't give them the freedom to make the most of the chance you have given them?

I'm hopeful that after Iraq, those in charge will think twice about taking us down that route again.

When I was young, every time I criticized someone, my mother would stand me in front of the mirror and say: 'The flaws you see in others are actually a reflection of yourself.' That taught me to pay close attention when I looked at others.

On conflicts, generally speaking, the world is a hell of a lot better to live in today than it was thirty years ago, despite what's going on in Syria. There are definitely hopeful signs that the world is moving, decade by decade, in the right direction.

There isn't a flight goes by when I don't stare out of the window and thank my stars for what I'm seeing and feeling.

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.
