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. I did not wish to live what was not life, living is do dear; nor did I wish to practice resignation, unless it was quite necessary. I wanted to live deep and suck out all of the marrow of life, to cut a broad swatch and shave close, to drive life into a corner, and reduce it to its lowest terms. - Henry David Thoreau, Walden.
