More quotes by Henry David Thoreau, Walden

"I mean that they (students) should not play life, or study it merely, while the community supports them at this expensive game, but earnestly live it from beginning to end. How could youths better learn to live than by at once trying the experiment of living? Methinks this would exercise their minds as much as mathematics."
"All men want, not something to do with, but something to do, or rather something to be."
"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."
"Things do not change; we change."
"How many a man has dated a new era in his life from the reading of a book."
