The person who has lived the most is not the one with the most years but the one with the richest experiences.
Life isn't worth living, unless it is lived for someone else.
Living is like tearing through a museum. Not until later do you really start absorbing what you saw, thinking about it, looking it up in a book, and remembering - because you can't take it in all at once.
Don't go around saying the world owes you a living. The world owes you nothing. It was here first.
It is too difficult to think nobly when one thinks only of earning a living.
