Man is subject to innumerable pains and sorrows by...

The stars shall fade away, the sun himself Grow dim with age, and nature sink in years, But thou shalt flourish in immortal youth, Unhurt amidst the wars of elements, The wrecks of matter, and the crush of worlds.

Young men soon give, and soon forget, affronts old age is slow in both.

It is folly for an eminent man to think of escaping censure, and a weakness to be affected with it. All the illustrious persons of antiquity, and indeed of every age in the world, have passed through this fiery persecution.

Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young. The greatest thing in life is to keep your mind young.

There is a fountain of youth: it is your mind, your talents, the creativity you bring to your life and the lives of people you love. When you learn to tap this source, you will truly have defeated age.

Life would be infinitely happier if we could only be born at the age of eighty and gradually approach eighteen.

Probably the happiest period in life most frequently is in middle age, when the eager passions of youth are cooled, and the infirmities of age not yet begun as we see that the shadows, which are at morning and evening so large, almost entirely disappear at midday.

He who is of 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.

The stars shall fade away, the sun himself Grow dim with age, and nature sink in years, But thou shalt flourish in immortal youth, Unhurt amidst the wars of elements, The wrecks of matter, and the crush of worlds.

To be happy, we must be true to nature and carry our age along with us.
