A few quotations

• "Chains of habit are too light to be felt until they are too heavy to be broken." --- Warren Buffett
• "More is in vain if less will serve." --- Issac Newton
• "Say what you know, do what you must, come what may."   --- Sofia Kovalevskaya
• "The life of man is a long march through the night, surrounded by invisible foes, tortured by weariness and pain, towards a goal that few can hope to reach, and where none may tarry long."   --- Bertrand Russell
• "Don't pray for an easier life, pray that you become stronger."   --- JFK
• "It is not the critic who counts: not the man who points out how the strong man stumbles or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly, who errs and comes up short again and again, because there is no effort without error or shortcoming, but who knows the great enthusiasms, the great devotions, who spends himself for a worthy cause; who, at the best, knows, in the end, the triumph of high achievement, and who, at the worst, if he fails, at least he fails while daring greatly, so that his place shall never be with those cold and timid souls who knew neither victory nor defeat." ---Theodore Roosevelt
• "I wish to preach, not the doctrine of ignoble ease, but the doctrine of the strenuous life, the life of toil and effort, of labor and strife; to preach that highest form of success which comes, not to the man who desires mere easy peace, but to the man who does not shrink from danger, from hardship, or from bitter toil, and who out of these wins the splendid ultimate triumph." ---Theodore Roosevelt
• "When I was 15, I was sent to live with my brother in Florida. One day when I was really hungry, I saw a lady and decided I would ask her if I could do anything around her house for something to eat. She was a white woman. And this woman took my mother's son, whom she has never met before, and fed me like my mother would have done. I came to understand what an internal sense of humanity is. That was a major point of my life." --- Sidney Poitier
• "... but I want to say I have complete empathy and admiration for his inner strength and clarity, to be able to know and hold true to himself. Our true needs are deeper -- yet in our modern society most of us reflexively and relentlessly pursue wealth, consumer goods and admiration. We have learned from Perelman's mathematics. Perhaps we should also pause to reflect on ourselves and learn from Perelman's attitude toward life." --- William Thurston (laudations in honor of Grigoriy Perelman)
