If you really understand something, you can: 1) explain it using a clear metaphor and 2) explain the strongest counter-argument to the idea.

Talk to people no one else is talking to. Who would have thought that giving a speech at a funeral at age 12 would introduce me to a man who would introduce me to my first business contact who would introduce me to several other important people in my life. That's luck. That's randomness.

I've always loved to write, and I kept a diary of what I thought about my business, being an entrepreneur and other things of interest to me.

One theme that fascinates me is cognitive enhancement. It seems only a matter of time until we live in a world where steroids for the brain are readily available to all. And once we come to grips with that reality, I suspect the debate over the ethics will be much more heated than the debate over steroids in baseball or any other sport, where the use is limited to a select group of freakish athletes.

Long-term goals are dangerous. They limit you. They hinder you from reacting to new conditions.

Expose yourself to as much randomness as possible.

The internet tends to make smart people smarter and dumb people dumber.
