We pay when old for the excesses of youth.

In youth we run into difficulties. In old age difficulties run into us.

Middle age is youth without levity and age without decay.

In youth the days are short and the years are long. In old age the years are short and day's long.

Youth is the best time to be rich and the best time to be poor.

Aging is not lost youth but a new stage of opportunity and strength.

As long as any adult thinks that he like the parents and teachers of old can become introspective invoking his own youth to understand the youth before him he is lost.

There is always some specific moment when we become aware that our youth is gone but years after we know it was much later.

Youth is the gift of nature but age is a work of art.

Forty is the old age of youth fifty is the youth of old age.
