Space is not a two-year objective. It used to be, in the early '60's, we had this eye candy of Mercury and Gemini and Apollo and every year we would do something more and more and it met those needs. But the easy stuff has been done.

If you give people unlimited time and money, they'll do things the same old way. But if they have to achieve the goal in a brief time, they'll either give up or try something new.

Small teams driven by their passion with a clear focus can do extraordinary things. Things that only large corporations and governments could do in the past.

The first trillionaire can be made in space.

Find that thing that you are passionate about, that you will do day or night whether someone pays you or not...because if you have that, you will have gold.

Imagine a world of nine billion people with clean water, nutritious food, affordable housing, personalized education, top-tier medical care, and nonpolluting, ubiquitous energy. Building this better world is humanity's grandest challenge.

I have the general philosophy of creating the future you want to see.
