Doing your best means never stop trying.

I do the very best I know how, the very best I can, and I mean to keep on doing so until the end

Things may come to those who wait...but only the things left by those who hustle.

I don't like that man. I must get to know him better.

I can see how it might be possible for a man to look down upon the earth and be an atheist, but I cannot conceive how he could look up into the heavens and say there is no God.

If I were to try to read, much less answer, all the attacks made on me, this shop might as well be closed for any other business. I do the very best I know how -- the very best I can. And I mean to keep on doing it to the end. If the end brings me out all right, what is said against me will not amount to anything. If the end brings me out all wrong, ten angels swearing I was right would make no difference.
