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

Preparation for old age should begin not later than one's teens. A life which is empty of purpose until 65 will not suddenly become filled on retirement.

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

Growing old is no more than a bad habit which a busy person has no time to form.

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.
