I have a collection of quotes that I started last year. Over that time it's grown to be quite large. For your reading pleasure, here are a few of my favorites.
"To try when it seems there is no hope is to risk failure, but not to try is to guarantee it" - Anonymous
"The man who insists on seeing with perfect clearness before he decides, never decides." - Henri-Frederic Amiel
"Human beings are the only creatures that allow their children to come back home." - Bill Cosby
"The wages of sin are death, but by the time taxes are taken out, it's just sort of a tired feeling." - Paula Poundstone
"The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents." - HP Lovecraft
