I loved every minute of my time at Microsoft, but I had always envisioned having another phase of life just because I thought that would be interesting. It had never been my plan to work until I literally didn't want to do anything and then hang it up.

The company I invested in is probably a leader in that area. They're a company called Second Spectrum, which happens to be based in LA but was started by two USC computer-science professors. It's filled with guys who love sports, who played sports, but really look like programmers.

In terms of the public positioning of the company, Satya's [Nadella] done a very good job. He sort of pivoted in a way that I don't think would have been possible for me to do even if I'd seen it that way, to really talk about this mobile-first, cloud-first world.

I've been doing lot of work, and hopefully will bring it to fruition in a way people can see it, really understanding - this is going to sound funny, but what does government really do, how is it really funded, and what measures exist to evaluate how it does at what it does? No forecast, no policy, no prediction, just a realistic perspective on what is. Call it like a "10k for government" we've been working on with a website, with additional data.

If you look at companies with upside potential, Twitter's right there. They've established a brand in a world where it's extremely difficult to establish a brand. It's a global brand, people recognize it, people want to let you know what their Twitter handles are, etc.

So, I think the output of our innovation is great. We have a culture of self-improvement. I know we can continue to improve. There is no issue. But at the same time, our absolute level of output is fantastic.

Look at the product pipeline, look at the fantastic financial results we've had for the last five years. You only get that kind of performance on the innovation side, on the financial side, if you're really listening and reacting to the best ideas of the people we have.
