To serve is beautiful, but only if it is done with joy and a whole...

We should so provide for old age that it may have no urgent wants of this world to absorb it from meditation on the next. It is awful to see the lean hands of dotage making a coffer of the grave.

You can judge your age by the amount of pain you feel when you come in contact with a new idea.

Inside myself is a place where I live all alone and that is where I renew my springs that never dry up.

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.

Age is an issue of mind over matter. If you don't mind, it doesn't matter.

Common sense is the collection of prejudices acquired by age eighteen.

The older I grow the more I distrust the familiar doctrine that age brings wisdom.

Wisdom doesn't necessarily come with age. Sometimes age just shows up all by itself.
