We are happier in many ways when we are old than when we were young. The young sow wild oats. The old grow sage.

Any attempts at autobiography before the age of eighty seem pretty self-involved to me. There are a lot of smart middle aged people but not many wise ones.

You take all the experience and judgment of men over 50 out of the world and there wouldn't be enough left to run it.

Learning acquired in youth arrests the evil of old age; and if you understand that old age has wisdom for its food, you will so conduct yourself in youth that your old age will not lack for nourishment.

Wisdom is the daughter of experience.

Even the hard times are part of your life story. If you acknowledge them and move past them, they eventually add up to the experience that makes you wise.
