Commonly men will only be brave as their fathers were brave,... - Henry David Thoreau, Walden

"The cost of a thing is the amount of what I will call life which is required to be exchanged for it, immediately or in the long run."

"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."

"As if you could kill time without injuring eternity."

"Only that day dawns to which we are awake. There is more day to dawn. The sun is but a morning star."
