I'd never taken an SAT prep course. They were for weaker students.

The question was, in a sense, at Princeton Review, how much value was I adding as a public company CEO. I was adding less than other people might've... I think you want to move on when you've given your best work and then feel that you're not going to add as much value moving forward.

The Internet is the first technology since the printing press which could lower the cost of a great education and, in doing so, make that cost-benefit analysis much easier for most students. It could allow American schools to service twice as many students as they do now, and in ways that are both effective and cost-effective.

I hated being a public company CEO.

I studied to be an architect. And I find tremendous similarities between building a company and the design process. Businesses have to do their planning on the fly in a fashion similar to an architect sketching.

The Internet rewards scale; by trading higher up-front costs for lower marginal cost, market leaders can invest in better technology and service. As a result, there is nothing online that is both great in quality and small in scale. Amazon wasn't originally a better bookstore than the small shops we mourn, but it is now.

Exciting discoveries in neuroscience are allowing us to fit educational methods to new understandings of how the brain develops.
