I've been collecting quotes from a variety of sources for several years now. These are some of my favourites.

"When it's dark enough, you can see the stars."

"Look thou be true: do not give dalliance
Too much the rein: the strongest oaths are straw
To th' fire i' th' blood. Be more abstemious,
Or else good night your vow!"

"Purpose is but the slave to memory . . .
What to ourselves in passion we propose,
The passion ending, doth the purpose lose."

"Few men have the strength to honor a friend's success without envy."

"Even the darkest night will end and the sun will rise."

"Tell the truth and shame the devil."

"Just because you're paranoid doesn't mean you're not being followed."

"Trust in God for a new kinda life. Honey, He won't lead you astray."

"Who of you by worrying can add a single hour to his life?... Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own."

"Only boring people get bored."

"There's more to see than can ever be seen
More to do than can ever be done
There's far too much to take in here
More to find than can ever be found"

"We read to know we're not alone."

"Life is a brief moment between two vast eternities. What will you do with your moment?"

"Most Christians trust Christ for their eternity, but not for the next twenty-four hours."

"He throws our sins in the deepest sea, and then He puts up a 'No Fishing' sign."

"Each redwood has an embarrassing secret: a very shallow root system. So God ordained that they clump together, interlacing their roots, to hold each other up when the storms howl."

"Attack me, I do this myself, but attack me rather than the path I follow and which I point out to anyone who asks me where I think it lies. If I know the way home and am walking along it drunkenly, is it any less the right way because I am staggering from side to side!"

"The world may call the poor inferior, but they are not... It is your clothing that is better, not you. The poor one is a person, and what are you more than that?"
