Youthfulness

Youth is happy because it has the ability to see beauty. Anyone who keeps the ability to see beauty never grows old.

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

I'm not interested in age. People who tell me their age are silly. You're as old as you feel

If wrinkles must be written upon our brows, let them not be written upon the heart. The spirit should never grow old
