We will eventually build space science labs and hotels, prodding the capability for missions beyond the orbit of the Earth. Our space-hotel guests will be able to take breath-taking excursions, flying a couple of hundred feet above the Moon's surface in small two-man spaceships. In time, we will launch missions to Mars and beyond.

Nothing else even comes close.

I have enjoyed life a lot more by saying "yes" than by sayings "no".

I will work day and night to avoid failure, but if I can't, I'll pick myself up the next day. The most important thing for entrepreneurs is not to be put off by failure.

If you take care of your workers they'll take care of your business.

I believe that drudgery and clock-watching are a terrible betrayal of that universal, inborn entrepreneurial spirit.

Never to be frightened of taking risks and always follow your instincts!
