“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 so dear; nor did I wish to practise resignation, unless it was quite necessary. I wanted to live deep and suck out all the marrow of life, to live so sturdily and Spartan-like as to put to rout all that was not life, to cut a broad swath and shave close, to drive life into a corner, and reduce it to its lowest terms.”  ― Henry David Thoreau, Walden: Or, Life in the Woods


“我步入丛林，因为我希望生活的有意义，我希望活的深刻，并汲取生命中所有的精华。然后从中学习，以免让我在生命终结时，却发现自己从来没有活过。”  ——梭罗 《瓦尔登湖》
