Man, I'm having a hard time trying to remember actual good quotes. These are definitely in my top.
"There are three things all wise men fear: the sea in storm, a night with no moon, and the anger of a gentle man." Patrick Rothfuss, A WISE MAN'S FEAR.
"Meanest dog you'll ever meet -
It ain't the hound dog in the street.
He bares his teeth and tears your skin
But brother, that's the worst of him.
The dog you really got to dread
Is the one that howls inside your head.
It's him whose howling drives men mad
And a mind to its undoing.
You got a lonesome road to walk.
It ain't along the railroad track.
It ain't along the black-top tar
You've walked a hundred times before.
I'll tell you where the real road lies:
Between your ears, behind your eyes.
That is the path to Paradise,
And, likewise, the road to ruin" Hermes, HADESTOWN
