"I am only one, but I am one.
I cannot do everything, but I can do something.
And because I cannot do everything,
I will not refuse to do the something that I can do.
What I can do, I should do.
And what I should do, by the grace of God, I will do."
The Book of Good Cheer : A Little Bundle of Cheery Thoughts? (1909) by Edwin Osgood Grover, p. 28
