“That some achieve great success, is proof to all that others can achieve it as well.”

“Four score and seven years ago our fathers brought forth on this continent a new nation, conceived in liberty and dedicated to the proposition that all men are created equal. Now we are engaged in a great civil war, testing whether that nation or any nation so conceived and so dedicated can long endure. We are met on a great battlefield of that war. We have come to dedicate a portion of that field as a final resting-place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this. But in a larger sense, we cannot dedicate, we cannot consecrate, we cannot hallow this ground. The brave men, living and dead who struggled here have consecrated it far above our poor power to add or detract. The world will little note nor long remember what we say here, but it can never forget what they did here. It is for us the living rather to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us — that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion — that we here highly resolve that these dead shall not have died in vain, that this nation under God shall have a new birth of freedom, and that government of the people, by the people, for the people shall not perish from the earth.” 

“Allow me to assure you it is a perfect certainty that you will, very soon, feel better - quite happy - if you only stick to the resolution you have taken to procure a military education. I am older than you, have felt badly myself, and know, what I tell you is true. Adhere to your purpose and you will soon feel as well as you ever did. On the contrary, if you falter, and give up, you will lose the power of keeping any resolution, and will regret it all you life.”

“I have never studied the art of paying compliments to women; but I must say that if all that has been said by orators and poets since the creation of the world in praise of women were applied to the women of America, it would not do them justice for their conduct during this war.”

“On peut tromper une partie du peuple tout le temps et tout le peuple une partie du temps, mais on ne peut pas tromper tout le peuple tout le temps.”

“The best way to predict your future is to create it.”

“If you once forfeit the confidence of your fellow citizens, you can never regain their respect and esteem. It is true that you may fool all of the people some of the time; you can even fool some of the people all of the time; but you can't fool all of the people all of the time. -Speech at Clinton, Illinois, September 8, 1854.”

“Die when I may, I want it said of me by those who know me best, that I always plucked a thistle and planted a flower when I thought a flower would grow.”

“With malice toward none, with charity for all, with firmness in the right as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation's wounds, to care for him who shall have borne the battle and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves and with all nations.”
