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.

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.

Usually youth is for freedom and reform, maturity for judicious compromise, and old age for stability and repose.

Supreme happiness will be the greatest cause of misery, and the perfection of wisdom the occassion of folly.

Experience is a truer guide than the words of others.
