I think entrepreneurship is our natural state--a big adult word that probably boils down to something much more obvious like playfulness.

I have always lived my life by thriving on opportunity and adventure. Some of the best ideas come out of the blue, and you have to keep an open mind to see their virtue.

My philosophy is that if I have any money I invest it in new ventures and not have it sitting around.

Communication: the thing humans forgot when we invented words.

Business has to give people enriching, rewarding lives...or it's simply not worth doing.

We've definitely cracked the technology. Now we're just trying to be able to produce the amount of fuels that we need to satisfy our own needs and then other people's needs.

Focus on your business strengths and keep its weaknesses away from the competition or public.
