Almost three years ago, when I retired, my wife and I were talking about our philanthropic work and how does one help give opportunity, particularly to kids growing up in very disadvantaged situations.And my initial kind of sense was, the government does that primarily, and what we should mostly do is pay our taxes. My wife said, no, I don't think that's quite right for us. We need to do more. We can do better.

I'm a shareholder in Microsoft Corp. of some size, and while I don't work for the place anymore, I think a lot about that investment, how - as an outsider - might I add value or not add value? Do I believe that things are headed in a good direction? So I wouldn't say I spend the majority of my time on that, but I spend some time on that as well.

We don't have a monopoly. We have market share. There's a difference.

In general, I'm pretty busy with the other things I charted ... I bought a piece of a sports-tech company. We do a lot of work with at the Clippers. I think that'll be great. We're really looking at the possibility of extending and building a real over-the-top distribution channel with value-added services for the Clippers, that could lead to other partnerships and investments. But most of the stuff I'm looking at isn't because I say, "Hey, I want to invest." It sort of comes around from the work we're doing with the Clippers.

There is such an overvaluation of technology stocks that it is absurd. I would include our stock in that category. It is bad for the long-term worth of the economy.

You get some success. You run into some walls...it's how tenacious you are, how irrepressible, how ultimately optimistic and tenacious you are about it that will determine your success.

I think it would be absolutely reckless and irresponsible for anyone to try and break up Microsoft.
