“no man who is resolved to make the most of himself can spare time for personal contention, still less can he afford to take the consequences, including the vitiation of his temper and the loss of self control, yield to larger things to which you show no more than equal rights, and yield to lesser ones though clearly your own, better give your path to a dog, than be bitten by him in contesting for the right, not even killing the dog, will cure the bite”

“Believing everyone is dangerous, but believing nobody is more dangerous.”

“Rules of living Don't worry, eat three square meals a day,say your prayers, be courteous to your creditors, keep your digestion good,steer clear of biliousness,exercise, go slow and go easy.

“It is the eternal struggle between these two principles — right and wrong — throughout the world. They are the two principles that have stood face to face from the beginning of time; and will ever continue to struggle. The one is the common right of humanity, and the other the divine right of kings. It is the same principle in whatever shape it develops itself. It is the same spirit that says, "You toil and work and earn bread, and I'll eat it." No matter in what shape it comes, whether from the mouth of a king who seeks to bestride the people of his own nation and live by the fruit of their labor, or from one race of men as an apology for enslaving another race, it is the same tyrannical principle.”

“You can lose everything in life,but not dreams.”

“you can fool some of the people all of the time and all of the people some of the time but you cannot fool all of the people all of the time”

“Without the assistance of that divine being, I cannot succeed. With that assistance I cannot fail. Trusting in Him, who can go with me, remain with you and be everywhere for good let us confidently hope that all will yet be well.”

“This is a world of compensation; and he who would be no slave must consent to have no slave. Those who deny freedom to others deserve it not for themselves, and, under a just God, cannot long retain it.”

“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.”
