Life appears to me too short to be spent in nursin...

Memory in youth is active and easily impressible in old age it is comparatively callous to new impressions, but still retains vividly those of earlier years.

I feel monotony and death to be almost the same.

The human heart has hidden treasures, In secret kept, in silence sealed The thoughts, the hopes, the dreams, the pleasures, Whose charms were broken if revealed.

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.
