In a hyper-connected world where average is over, there is one thing we know absolutely for sure: Every good job will require more education.

Almost all the students who make it to Caltech, one of the best scientific universities in the world, come from public schools. So it can be done.

Optimists are usually wrong. But all the great change in history, positive change, was done by optimists.

You always have to remember that Mother Nature is a lot like your body. If your temperature goes from 98.6 to 100.6, you don't feel so good. If it goes from 100.6 to 102.6, well, you call the doctor. If it goes from 102.6 to 104.6, you're in the emergency room at a hospital. The same with Mother Nature - small changes in global average temperatures have a huge climate effect.

The reason that we are becoming less equal is because of the greater requirements, secure requirements, for a good job. This goes back to the '80s basically, this started changing as globalization and the IT revolution merged, and each started to drive the other.

Change your leaders, not your light bulbs.

The hidden hand of the market will never work without a hidden fist.
