“if you don't have peace, it isn't because someone took it from you; you gave it away. You cannot always control what happens to you, but you can control what happens in you.”

“Love is something more stern and splendid than mere kindness.”

“desire is the catalyst that enables a person with average ability to compete and win against others with more natural talent.” 

“Is that the name you wish, Muad’Dib?” Stilgar asked. “I am an Atreides,” Paul whispered, and then louder: “It’s not right that I give up entirely the name my father gave me. Could I be known among you as Paul-Muad’Dib?” “You are Paul-Muad’Dib,” Stilgar said.

“The right to search for the truth implies also a duty; one must not conceal any part of what one has recognized to be the truth.”

“I have to live with myself, and so I want to be fit for myself to know, I want to be able, as days go by, Always to look myself straight in the eye; I don’t want to stand, with the setting sun, And hate myself for things I have done. I don’t want to keep on a closet shelf A lot of secrets about myself, And fool myself, as I come and go, Into thinking that nobody else will know The kind of man I really am; I don’t want to dress up myself in sham. I want to go out with my head erect, I want to deserve all men’s respect; But here in the struggle for fame and pelf I want to be able to like myself. I don’t want to look at myself and know That I’m bluster and bluff and empty show. I can never hide myself from me; I see what others may never see; I know what others may never know, I never can fool myself, and so, Whatever happens, I want to be Self-respecting and conscience free.”

“Some men look at constitutions with sanctimonious reverence, and deem them like the ark of the covenant, too sacred to be touched. They ascribe to the men of the preceding age a wisdom more than human, and suppose what they did to be beyond amendment. I knew that age well; I belonged to it, and labored with it. It deserved well of its country. It was very like the present, but without the experience of the present; and forty years of experience in government is worth a century of book-reading; and this they would say themselves, were they to rise from the dead. I am certainly not an advocate for frequent and untried changes in laws and constitutions. I think moderate imperfections had better be borne with; because, when once known, we accommodate ourselves to them, and find practical means of correcting their ill effects. But I know also, that laws and institutions must go hand in hand with the progress of the human mind. As that becomes more developed, more enlightened, as new discoveries are made, new truths disclosed, and manners and opinions change with the change of circumstances, institutions must advance also, and keep pace with the times. We might as well require a man to wear still the coat which fitted him when a boy, as civilized society to remain ever under the regimen of their barbarous ancestors.” 

“The most valuable lessons in life do not come when you are walking or running. They come when you fall down. You better take them and rise up!”

“Fear tries to get us to give up but faith takes us all the way through to victory”

“there are five nonnegotiable characteristics that every effective leader must have: a sense of calling, an ability to communicate, creativity in problem solving, generosity, and consistency.”

“The ultimate weakness of violence is that it is a descending spiral, begetting the very thing it seeks to destroy. Instead of diminishing evil, it multiplies it. Through violence you may murder the liar, but you cannot murder the lie, nor establish the truth. Through violence you murder the hater, but you do not murder hate. In fact, violence merely increases hate. Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that.”
