My mother felt we'd be earning a living during our entire adult lives, and therefore believed we should spend summers in learning activities. Consequently, I got to see a plate glass factory in Pittsburgh, a U.S. Steel plant, and how Heinz made ketchup.

I've always enjoyed seeing how things are made.

It's clear there is an energy positive in producing ethanol.

Mom worked as a school librarian, and she felt summers were for education.

I don't feel that my marriage has anything to do with my career. It never hampers anyone's career in the film industry.

When a nanotech company matures and becomes a real business, it becomes something else. It becomes a biotech company or a cleantech company or a memory chip company. Nanotechnology has fueled the core innovations in electronics and energy.

Regardless if your career is short or long, I personally would rather win more often than not.

You should never have regrets in life. All the steps that I have taken in my career have served for something, and I have learned from them.
