Never look back unless you are planning to go that way. - Henry David Thoreau

"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."

"Thank God men cannot fly, and lay waste the sky as well as the earth."

"It's not what you look at that matters, it's what you see."

"Pursue some path, however narrow and crooked, in which you can walk with love and reverence."

"How vain it is to sit down to write when you have not stood up to live."
