It's just mind-blowingly awesome. I apologize, and I wish I was more articulate, but it's hard to be articulate when your mind's blown-but in a very good way.

When something is important enough, you do it even if the odds are not in your favor.

I don't spend my time pontificating about high-concept things; I spend my time solving engineering and manufacturing problems.

A Prius is not a true hybrid, really. The current Prius is, like, 2 percent electric. It's a gasoline car with slightly better mileage.

The only reason I was able to accomplish things is the great people willing to work with me. A company is a group of people organized to create a product or service, and that product or service is only as good as the people in the company - and how excited they are about creating it. I do want to recognize a ton of super-talented people. Without them, I would have accomplished very little. I just happen to be the face of the companies.

I think life on Earth must be about more than just solving problems... It's got to be something inspiring, even if it is vicarious.
