“Hardship can humble you, but it cannot break you unless you let it. Your instinct for survival will see you through if you’re attuned to its frequency. Instinct will find a temporary stopgap without ever taking its sights off your larger goals. There’s no greater way to hone your instincts than to overcome adversity.”

“The world will be a better place when everyone becomes a leader; when everyone finds what he/she was sent to do and does it like no other man’s business.”

“Yo debo gobernar el reloj, no ser gobernada por él”

“In the temple of science are many mansions, and various indeed are they that dwell therein and the motives that have led them thither. Many take to science out of a joyful sense of superior intellectual power; science is their own special sport to which they look for vivid experience and the satisfaction of ambition; many others are to be found in the temple who have offered the products of their brains on this altar for purely utilitarian purposes. Were [someone to] drive all the people belonging to these two categories out of the temple, the assemblage would be seriously depleted, but there would still be some men, of both present and past times, left inside. Our Planck is one of them, and that is why we love him.”

“Do the one thing you think you cannot do. Fail at it. Try again. Do better the second time. The only people who never tumble are those who never mount the high wire.” 

“Candler—mixed with the secret formula was. . . IMAGINATION!”

“Do as she says, you wormfaced, crawling, sand-brained piece of lizard turd!”

“Lamentably, it is a historical fact that privileged groups seldom give up their privileges voluntarily. Individuals may see the moral light and voluntarily give up their unjust posture; but, as Reinhold Niebuhr has reminded us, groups tend to be more immoral than individuals.”

“Numerous are the academic chairs, but rare are wise and noble teachers. Numerous and large are the lecture halls, but far from numerous the young people who genuinely thirst for truth and justice. Numerous are the wares that nature produces by the dozen, but her choice products are few. We all know that, so why complain? Was it not always thus and will it not always thus remain? Certainly, and one must take what nature gives as one finds it. But there is also such a thing as a spirit of the times, an attitude of mind characteristic of a particular generation, which is passed on from individual to individual and gives its distinctive mark to a society. Each of us has to his little bit toward transforming this spirit of the times.” 

“I live in that solitude which is painful in youth, but delicious in the years of maturity.”

“Success requires no explanations. Failure permits no alibis.”

“I have a dream that one day this nation will rise up and live out the true meaning of its creed: "We hold these truths to be self-evident, that all men are created equal." I have a dream that one day on the red hills of Georgia, the sons of former slaves and the sons of former slave owners will be able to sit down together at the table of brotherhood. I have a dream that one day even the state of Mississippi, a state sweltering with the heat of injustice, sweltering with the heat of oppression, will be transformed into an oasis of freedom and justice. I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. I have a dream today! I have a dream that one day, down in Alabama, with its vicious racists, with its governor having his lips dripping with the words of "interposition" and "nullification" -- one day right there in Alabama little black boys and black girls will be able to join hands with little white boys and white girls as sisters and brothers. I have a dream today! I have a dream that one day every valley shall be exalted, and every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight; "and the glory of the Lord shall be revealed and all flesh shall see it together.”

“serving is the highest use of life,”

“God provides something to you through somebody. Thats same God can give something to somebody through you. If you make yourself a greedy traffic on the way and deprive the final destined owner of what you supposed to keep provisionally, you make God upset.”

“Don’t cry out to God for change, and then be afraid of it when it comes.”
