I think over any period of time, especially if you don't use leverage, it is difficult to continually beat the S&P 500.

I learned to embrace risk, as long as it was well thought out and, in a worst-case scenario, I'd still land on my feet.

I can imagine no more important contribution to our country's future than a long-term commitment to improving urban K-12 public schools.

Someone once told me I'm a sore winner, and they're right. I rarely take more than a moment to enjoy a success before I'm moving on and looking for the next challenge.

You can have great teachers, but if you don't have a good principal, you won't have a good school.
