You've got to have models in your head. And you've got to array your experience — both vicarious and direct — on this latticework of models.

I constantly see people rise in life who are not the smartest, sometimes not even the most diligent, but they are learning machines. They go to bed every night a little wiser than they were when they got up and boy does that help, particularly when you have a long run ahead of you.

You must know the big ideas in the big disciplines and use them routinely — all of them, not just a few.

Life will have terrible blows, horrible blows, unfair blows. It doesn't matter. And some people recover and others don't. There I think the attitude of Epictetus is the best. He thought that every mischance in life was an opportunity to behave well — an opportunity to learn something.
