But it is not the job of truth to make us feel good. It is the job of truth to be true, and it is our job to deal with it.

Thinking means concentrating on one thing long enough to develop an idea about it. Not learning other people's ideas, or memorizing a body of information, however much those may sometimes be useful. Developing your own ideas. In short, thinking for yourself.

We proceed by doubt, by trial and error, by resisting the impulse to lunge after certainty.

There's no doubt about it: fun people are fun. But I finally learned that there is something more important, in the people you know, than whether they are fun. Thinking about those friends who had given me so much pleasure but who had also caused me so much pain, thinking about that bright, cruel world to which they'd introduced me, I saw that there's a better way to value people. Not as fun or not fun, or stylish or not stylish, but as warm or cold, generous or selfish. People who think about others and people who don't. People who know how to listen, and people who only know how to talk.

Don't play it safe. Resist the seductions of the cowardly values our society has come to prize so highly: comfort, convenience, security, predictability, control. These, too, are nets. Above all, resist the fear of failure. Yes, you will make mistakes. But they will be your mistakes, not someone else's. And you will survive them, and you will know yourself better for having made them, and you will be a fuller and a stronger person.

If you're oblivious to other people, chances are pretty good that you're going to hurt them.
