Never go into business purely to make money. If that's the motive you're better off doing nothing.

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.

Everybody has a camera on their phone these days, everybody wants a selfie or a picture, and the moment one person starts taking a picture everybody congregates around so I've become quite a fast walker. I don't like saying, "No," to people but by walking fast one might be able to avoid the first photo.

I have always lived my life by making lists: lists of people to call, lists of ideas, lists of companies to set up, lists of people who can make things happen. Each day I work through these lists, and that sequence of calls propels me forward.

Be authentic and organic. It can't be forced or it won't work. And most importantly, have fun.
