Theodore Roosevelt
You are never too old to set another goal or to dream a new dream.
C.S Lewis

Mark Twain
Count your age by friends, not years. Count your life by smiles, not tears.
John Lennon

Oscar Wilde
Old age is like everything else. To make a success of it, you've got to start young.

Aristotle
The older I get, the greater power I seem to have to help the world; I am like a snowball - the further I am rolled the more I gain.
Susan B. Anthony
Life would be infinitely happier if we could only be born at the age of eighty and gradually approach eighteen.
