I'm insatiably curious about human nature.

We know from myths and fairy tales that there are many different kinds of powers in this world. One child is given a light saber, another a wizard's education. The trick is not to amass all the different kinds of power, but to use well the kind you've been granted.

When you go to a football game and someone offers you a beer [...], they're really saying hi, have a glass of extroversion.

What looks like multitasking is really switching back and forth between multiple tasks, which reduces productivity and increases mistakes by up to 50 percent.

The same person who finds it difficult to introduce himself to strangers might establish a presence online and then extend these relationships into the real world.

I get a lot of letters from introverts asking how they can meet people. The key is to make sure that you are doing things you enjoy.
