It is not the critic who counts; not the one who points out how the strong person stumbles, or where the doer of deeds could have done them better. The credit belongs to the person who is actually in the arena, whose face is marred by the dust and sweat and blood; who strives valiantly; who errs, and comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows the great enthusiasms, the great devotions; who spends himself or herself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he or she fails, at least fails while daring greatly, so that his or her place shall never be with those cold and timid souls who know neither victory nor defeat.

— Teddy Roosevelt

Judge a man by his questions rather than his answers.

— voltaire

The only guide to a man is his conscience; the only shield to his memory is the rectitude and sincerity of his actions. It is very imprudent to walk through life without this shield, because we are so often mocked by the failure of our hopes and the upsetting of our calculations; but with this shield -- however the fates may play -- we march always in the ranks of honor.

— Winston Churchill

Security is mostly a superstition. It does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than outright exposure. Life is either a daring adventure or nothing.

— Helen Keller

We must learn to live together as brothers or perish together as fools.

— Martin Luther King

If a man is called to be a streetsweeper, he should sweep streets even as Michelangelo painted, or Beethoven played music, or Shakespeare wrote poetry. He should sweep streets so well that all the hosts of heaven and earth will pause to say, here lived a great streetsweeper who did his job well.  

— Martin Luther King

Everyone takes the limits of his own vision for the limits of the world.

There are only two ways to live your life. One is as though nothing is a miracle. The other is as though everything is a miracle.

— Albert Einstein

The finest emotion of which we are capable is the mystic emotion. Herein lies the germ of all art and all true science. Anyone to whom this feeling is alien, who is no longer capable of wonderment and lives in a state of fear is a dead man. To know that what is impenetrable for us really exists and manifests itself as the highest wisdom and the most radiant beauty, whose gross forms alone are intelligible to our poor faculties - this knowledge, this feeling ... that is the core of the true religious sentiment. In this sense, and in this sense alone, I rank myself among profoundly religious men.

— Albert Einstein

We act as though comfort and luxury were the chief requirements of life, when all that we need to make us happy is something to be enthusiastic about.

Logic will get you from A to B. Imagination will take you everywhere.

— Albert Einstein

The intuitive mind is a sacred gift and the rational mind is a faithful servant. We have created a society that honors the servant and has forgotten the gift.

I am the happiest man alive. I have that in me that can convert poverty to riches, adversity to prosperity, and I am more invulnerable than Achilles; fortune hath not one place to hit me.

— Sir Thomas Browne

It was one of those days when it's a minute away from snowing and there's this electricity in the air, you can almost hear it. And this bag was, like, dancing with me. Like a little kid begging me to play with it. For fifteen minutes. And that's the day I knew there was this entire life behind things, and... this incredibly benevolent force, that wanted me to know there was no reason to be afraid, ever. Video's a poor excuse, I know. But it helps me remember... and I need to remember... Sometimes there's so much beauty in the world I feel like I can't take it, like my heart's going to cave in.

— Ricky Fitts in American Beauty

I had always heard your entire life flashes in front of your eyes the second before you die. First of all, that one second isn't a second at all, it stretches on forever, like an ocean of time... For me, it was lying on my back at Boy Scout camp, watching falling stars... And yellow leaves, from the maple trees, that lined my street... Or my grandmother's hands, and the way her skin seemed like paper... And the first time I saw my cousin Tony's brand new Firebird... And Janie... And Janie... And... Carolyn. I guess I could be pretty pissed off about what happened to me... but it's hard to stay mad, when there's so much beauty in the world. Sometimes I feel like I'm seeing it all at once, and it's too much, my heart fills up like a balloon that's about to burst... And then I remember to relax, and stop trying to hold on to it, and then it flows through me like rain and I can't feel anything but gratitude for every single moment of my stupid little life... You have no idea what I'm talking about, I'm sure. But don't worry... you will someday.

— Lester Burnham in American Beauty

I don’t have one minutes regret, it was a glorious experience.

Everything can be taken from a man but one thing: the last of the human freedoms -- to choose one's attitude in any given set of circumstances, to choose one's own way.

 — Viktor Frankl

Ultimately, man should not ask what the meaning of his life is, but rather he must recognize that it is he who is asked. 

— Viktor Frankl

After the day's struggle there is no freedom like unfettered thoughts, no sound like the music of silence. And though behind you lies a road of dust and heat and discouragement, and before you the challenge and uncertainty of untried paths, in this brief hour you are master of all highways, and the universe nestles in your soul.

— Max Ehrmann

When you have exhausted all possibilities, remember this — you haven't.

— Thomas A. Edison

I have missed more than 9,000 shots in my career. I have lost almost 300 games. On 26 occasions I have been entrusted to take the game winning shot, and I missed. I have failed over and over and over again in my life. And that is why I succeed.

Nothing has a stronger influence psychologically on their environment and especially on their children than the unlived life of the parent.

— C.G. Jung

Vigorous writing is concise. A sentence should contain no unnecessary words, a paragraph no unnecessary sentences, for the same reason that a drawing should have no unnecessary lines and a machine no unnecessary parts. This requires not that the writer make all his sentences short, or that he avoid all detail and treat his subjects only in outline, but that every word tell.

— William Strunk

This sentence has five words. Here are five more words. Five-word sentences are fine. But several together become monotonous. Listen to what is happening. The writing is getting boring. The sound of it drones. It’s like a stuck record. The ear demands some variety. Now listen. I vary the sentence length, and I create music. Music. The writing sings. It has a pleasant rhythm, a lilt, a harmony. I use short sentences. And I use sentences of medium length. And sometimes, when I am certain the reader is rested, I will engage him with a sentence of considerable length, a sentence that burns with energy and builds with all the impetus of a crescendo, the roll of the drums, the crash of the cymbals–sounds that say listen to this, it is important.

— Gary Provost

Any word you have to hunt for in a thesaurus is the wrong word.

— Stephen King

I apologize for the length of this letter but I didn't have time to make it shorter.
