“I will do what I can”
“What I can do, I will do. What I can't do, I will surrender to the one that can.”
“I do what I can do when I can do it.”
“I cannot do everything, but I can do something. And I won't let what I can't do get in the way of what I can.”
“I am only one, but I am one. I cannot do everything, but I can do something. And what I can do, I ought to do. And what I ought to do, by the grace of God, I shall do.”
“I can tell you what I wasn’t doing when I wasn’t doing what I was supposed to: I was doing what I was supposed to.”
