I en tråd som denne så er det vanskelig å komme unna klassikeren Walden - Livet i skogene av Henry David Thoreau; Denne ligger også i en internett-utgave på nasjonalbiblioteket -nb.no.
Leser for tiden essayet "Walking" hvor Thoreau hevder at enhver dag hvor man ikke har brukt minst fire timer ut på tur er en misbrukt dag(!).
-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.
-As a single footstep will not make a path on the earth, so a single thought will not make a pathway in the mind. To make a deep physical path, we walk again and again. To make a deep mental path, we must think over and over the kind of thoughts we wish to dominate our lives.
