If I can help somebody as I pass along, if I can cheer somebody with a word or song, if I can show somebody he's traveling wrong, then my living will not be in vain.
If I can do my duty as a Christian ought, if I can bring salvation to a world once wrought, if I can spread the message as the master taught, then my living will not be in vain.
- Martin Luther King, Jr. in The Autobiography of Martin Luther King, Jr.
