My wife thinks she's better than me at puzzles. I haven't given in on that one yet.

I try to make time for reading each night. In addition to the usual newspapers and magazines, I make it a priority to read at least one newsweekly from cover to cover. If I were to read what intrigues me- say, the science and business sections - then I would finish the magazine the same person I was when I started. So I read it all.

Every new change forces all the companies in an industry to adapt their strategies to that change.

Microsoft has some assets like Office that have stayed strong and there's so much room for innovation in those.

That's the part where the governments have a unique role, and then when it progresses well enough, then existing companies or new startup companies should take it. In the $3 trillion a year energy market, the rewards will be quite fantastic.

You have to have a certain realism that government is a pretty blunt instrument and without the constant attention of highly qualified people with the right metrics, it will fall into not doing things very well.

I never took a day off in my twenties. Not one. And I'm still fanatical, but now I'm a little less fanatical.
