Not by age but by capacity is wisdom acquired.

Some people die at age 25 and aren't buried until they are 75.

These are the arks, the trophies, I erect, That fortify thy name against old age.

Vigor is found in the man who has not yet grown old, and discretion in the man who is not too young.

Cast me not off in the time of old age; forsake me not when my strength faileth.

I remember my youth and the feeling that I could last forever, outlast the sea, the earth and all men.

Age in a virtuous person, of either sex, carries in it an authority which makes it preferable to all the pleasures of youth.

Cherish all your happy moments; they make a fine cushion for old age.

He who is of a calm and happy nature will hardly feel the pressure of age, but to him who is of an opposite disposition, youth and age are equally a burden.

There is a wisdom in this beyond the rules of physic. A man’s own observation, what he finds good of and what he finds hurt of, is the best physic to preserve health.

The wise man does at once what the fool does finally.

You are a fool in four letters, my son.

We should be careful to get out of an experience only the wisdom that is in it—and stop there; lest we be like the cat that sits down on a hot stove lid. She will never sit down on a hot stove lid again—and that is well; but also she will never sit down on a cold one any more.

Calmness of mind is one of the beautiful jewels of wisdom.
