Wisdom is the daughter of experience.

Although nature commences with reason and ends in experience it is necessary for us to do the opposite, that is to commence with experience and from this to proceed to investigate the reason.

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.

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.

If you hold a cat by the tail you learn things you cannot learn any other way.

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