There are exceptional people out there who are capable of starting epidemics. All you have to do is find them.

As human beings, we always expect everyday change to happen slowly and steadily, and for there to be some relationship between cause and effect.

There is a simple way to package information that, under the right circumstances, can make it irresistible. All you have to do is find it.

And my advice for college graduates is don't reflexively give money to your alma mater, something particular to Americans that I find extraordinary. Take Princeton, for example - it has more money on a per capita basis than any educational institution in the history of educational institutions.

I will say that without reservation.

There are some people, who I'll charitably call snobs, who are dismissive of any conversation that doesn't begin with the full level of complexity. That's just not how the world works.
