“Don't give up. Come on. Just keep on trying. Don't frown. Smile! You can do it. If you just try a little harder. I've got a feeling this whole thing might just work out okay. You'll see. Don't give up. Tomorrow is a brand new day. Now I want to see all of you get up on your feet and look like you're enjoying yourselves. Come on, let's see some of that famous ‘Pennsylvania optimism’ I've heard so much about..." [Excerpted from the recently discovered preamble to Gettysburg Address]”

“RESPONSE TO POLITICAL SMEAR TO ROBERT ALLEN New Salem, June 21, 1836 DEAR COLONEL:—I am told that during my absence last week you passed through this place, and stated publicly that you were in possession of a fact or facts which, if known to the public, would entirely destroy the prospects of N. W. Edwards and myself at the ensuing election; but that, through favor to us, you should forbear to divulge them. No one has needed favors more than I, and, generally, few have been less unwilling to accept them; but in this case favor to me would be injustice to the public, and therefore I must beg your pardon for declining it. That I once had the confidence of the people of Sangamon, is sufficiently evident; and if I have since done anything, either by design or misadventure, which if known would subject me to a forfeiture of that confidence, he that knows of that thing, and conceals it, is a traitor to his country’s interest. I find myself wholly unable to form any conjecture of what fact or facts, real or supposed, you spoke; but my opinion of your veracity will not permit me for a moment to doubt that you at least believed what you said. I am flattered with the personal regard you manifested for me; but I do hope that, on more mature reflection, you will view the public interest as a paramount consideration, and therefore determine to let the worst come. I here assure you that the candid statement of facts on your part, however low it may sink me, shall never break the tie of personal friendship between us. I wish an answer to this, and you are at liberty to publish both, if you choose. Very respectfully, A. LINCOLN.”

“We shall need all the anti-slavery feeling in the country, and more; you can go home and try to bring the people to your views, and you may say anything you like about me, if that will help...

“Nothing will divert me from my purpose.”
