There is a trade off - as you grow older you gain wisdom but you lose spontaneity.

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.

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.

It's good to learn from your mistakes. It's better to learn from other people's mistakes.

You learn from a conglomeration of the incredible past - whatever experience gotten in any way whatsoever.

We learn from experience that men never learn anything from experience.
