So I bought a journal specifically and exclusively for quotes. Thought provoking,funny, sad,etc. So I am asking YOU, yes you at the keyboard. To submit a quote, any quote. From The Bible to Neitzsche, Aristotle to Ozzy.
Ok I have one: “We are what we repeatedly do. Excellence then is not an act,but a habit”-Aristotle
“I was always embarrassed by the words sacred, glorious, and sacrifice and the expression in vain…abstract words such as glory, honor, courage or hallow were obscene beside the concrete names of villages, the numbers of roads, the names of rivers, the numbers of regiments and the dates.”
(Hemingway, A Farewell To Arms)
The Gorgon had surveyed the building again in the night, and had added the on stone face wanting; the stone face for which it had waited through about two hundred years.
It lay back on the pillow of Monsieur the Marquis. It was like a fine mask, suddenly startled, made angry, and petrified. Driven home into the heart of the stone figure attached to it, was a knife. Round the hilt was a frill of paper, on which was scrawled:
*‘Drive him fast to his tomb. This, from * JACQUES.’
-Charles Dickens, A Tale of Two Cities
Just one? 
Well, ok then:
“A great many people think they are thinking when they are merely rearranging their prejudices.” ~ William James
Or two or three: “We shall never surrender”-Winston Churchill

I hope that you don’t mind a passage. It’s from Carl Sagan’s The Demon-Haunted World:
“A mind stretched to a new idea never goes back to its original dimensions”

If I were to try to read, much less answer, all the attacks made on me, this shop might as well be closed for any other business. I do the very best I know how- the very best I can, and I mean to keep on doing so until the end. If the end brings me out all right, what is said against me won’t amount to anything. If the end brings me out wrong, 10 angels swearing I was right would make no difference. -Abraham Lincoln
We have a great deal more kindness than is ever spoken. Maugre all the selfishness that chills like east winds the world, the whole human family is bathed with an element of love like a fine ether. How many persons we meet in houses, whom we scarcely speak to, whom yet we honor, and who honor us! How many we see in the street, or sit with in church, whom, though silently, we warmly rejoice to be with! Read the language of these wandering eye-beams. The heart knoweth.

I can’t find a site or cite, but I recall from my youth:
“O pitiful race of a day, why do you make me say the obvious: that which is best is not attainable, not to be born; the next best is to die early”
Can any Dopers find the quote (IIRC, some (possibly conquering) soldiers (think ancient Greek times) had approached a sage and demanded that he answer the question 'What is Best in Life?")?
on second thought, make that:
“O pitiful race of a day, why do you make me say that which is better left unsaid: that which is best is not attainable, not to be born; the next best is to die early”.
I have no idea if this is the original quote you want. It may be paraphrased for Conan, but I found this:
“Conan, what is best in life?”
“To crush your enemies, see them driven before you, hear the lamentation of their women.”
- Conan The Barbarian
