I am only one, but I am one. I cannot do everything, but I can do something. And I will not let what I cannot do interfere with what I can do.
I am only one, but still I am one. I cannot do everything, but still I can do something; and because I cannot do everything, I will not refuse to do something I can do.
Never bear more than one kind of trouble at a time. Some people bear three kinds of trouble - the ones they've had, the ones they have, and the ones they expect to have.
