I take a simple view of life. It is keep your eyes...

I once asked a hermit in Italy how he could venture to live alone, in a single cottage, on the top of a mountain, a mile from any habitation? He replied, that Providence was his next-door neighbor.

Nothing is so perfectly amusing as a total change of ideas.

So much of motion, is so much of life, and so much of joy, and to stand still, or get on but slowly, is death and the devil.

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.
