As if you could kill time without injuring eternity. - Henry David Thoreau, Walden

"I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived."

"Not till we are lost, in other words not till we have lost the world, do we begin to find ourselves, and realize where we are and the infinite extent of our relations."

"How many a man has dated a new era in his life from the reading of a book."

"Things do not change; we change."

"All men want, not something to do with, but something to do, or rather something to be."
