I took a job at the Walt Disney Company and after 18 months decided to go to business school at Harvard. I was awestruck by the campus. My first reaction was I dont belong here. Then I said, Im here; lets get on with it.

CBS was very generous in their offer to re-sign me. But I simply want to try something new.

Take risks. Fail. Pick yourself back up again. And always, always remember this: there is no adversity capable of stopping you once the choice to persevere is made.

Look at the world around you & imagine it in a better way.

My prediction is that in the same way that Google is an intent revealing service that can be monetized that way, I would think that if I were at Twitter, I would focus on the search aspect of Twitter, because people are revealing intents when they do a search.

Theres nothing more intoxicating than doing big, bold things.

If you take a look at the way the premium content is monetized, there's a lot of different models out there. Sometimes you pay for an individual episode, for example on iTunes. Other times you pay for a subscription. And other times it's free ad-supported.
