“Persistence is a state of mind, therefore it can be cultivated. Like all states of mind, persistence is based upon definite causes,”

“Happiness depends upon ourselves.”

“I do not think that all who choose wrong roads perish; but their rescue consists in being put back on the right road. A sum can be put right: but only by going back til you find the error and working it afresh from that point, never by simply going on. Evil can be undone, but it cannot 'develop' into good. Time does not heal it. The spell must be unwound, bit by bit, 'with backward mutters of dissevering power' --or else not.”

“Willpower works for a few weeks, or maybe a month or two at best.” 

“it’s a human trait that when we encounter personal problems, those things most deeply personal are the most difficult to bring out for our logic to scan. We tend to flounder around, blaming everything but the actual, deep-seated thing that’s really chewing on us.”

“rule, once again, is that every minute spent in planning and creating checklists will save you ten minutes in execution and getting the job done

“Have you started already? Keep it up! Are you getting tired? Don't give up! Did you quit? You can do it again! Great accomplishments do not come with big steps; they come with little steps taken in regular installments! Do it and do it again and again!”

“No one could ride a horse if the horse discovered its real strength. The same thing is true for people.”

“Never be discouraged. The fact that you will be a winner at the first attempt is unclear. You don’t get master’s degree after attending school on the first day. You got to endure till you get there.”

“We know too well that our freedom is incomplete without the freedom of the Palestinians.”

“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 this government of the people, by the people, for the people, shall not perish from the earth.”

“There is an old Eastern fable about a traveler who is taken unawares on the steppes by a ferocious wild animal. In order to escape the beast the traveler hides in an empty well, but at the bottom of the well he sees a dragon with its jaws open, ready to devour him. The poor fellow does not dare to climb out because he is afraid of being eaten by the rapacious beast, neither does he dare drop to the bottom of the well for fear of being eaten by the dragon. So he seizes hold of a branch of a bush that is growing in the crevices of the well and clings on to it. His arms grow weak and he knows that he will soon have to resign himself to the death that awaits him on either side. Yet he still clings on, and while he is holding on to the branch he looks around and sees that two mice, one black and one white, are steadily working their way round the bush he is hanging from, gnawing away at it. Sooner or later they will eat through it and the branch will snap, and he will fall into the jaws of the dragon. The traveler sees this and knows that he will inevitably perish. But while he is still hanging there he sees some drops of honey on the leaves of the bush, stretches out his tongue and licks them. In the same way I am clinging to the tree of life, knowing full well that the dragon of death inevitably awaits me, ready to tear me to pieces, and I cannot understand how I have fallen into this torment. And Itry licking the honey that once consoled me, but it no longer gives me pleasure. The white mouse and the black mouse – day and night – are gnawing at the branch from which I am hanging. I can see the dragon clearly and the honey no longer tastes sweet. I can see only one thing; the inescapable dragon and the mice, and I cannot tear my eyes away from them. And this is no fable but the truth, the truth that is irrefutable and intelligible to everyone.

“When you’ve got a strong enough why, you can always find the how.” 

“Intellect has powerful muscles, but no personality.”

“I have examined all the known superstitions of the world,and I do not find in our particular superstition of Christianity one redeeming feature. They are all alike founded on fables and mythology. Millions of innocent men women and children since the introduction of Christianity,have been burnt, tortured, fined and imprisoned. What has been the effect of this coercion? To make one half the world fools and the other half hypocrites; to support roguery and error all over the earth.”
