If you're going to fail, you might as well fail at the big ones.

I think our society is no longer properly valuing the intangible potential of innovation, even if we have to be a little uncomfortable with the risks associated with it, and a little bit willing to fail, pick ourselves up and dust ourselves off and try again. We don’t seem to want to do that as much as we used too.

Segway will be to the car what the car was to the horse and buggy.

To me, innovations are the wheel, fire, language, movable type. There are not 3 million innovations; there are 3 million inventions

As we move towards 8 or 10 billion people on the planet, there's a little less gold per capita. Each one of us will continue to be fighting over an ever smaller percentage of total resources. This is not a happy thought

My biggest worry is I'm running out of time and energy. Thirty years ago I thought 10 years was a really long time.

An innovation is one of those things that society looks at and says, if we make this part of the way we live and work, it will change the way we live and work.
