“Every day is lost in which we do not learn something useful. Man has no nobler or more valuable possession than time.”

“We are always more anxious to be distinguished for a talent which we do not possess, than to be praised for the fifteen which we do possess.”

“We learn something every day, and lots of times it's that what we learned the day before was wrong.”

“It is a surprising and memorable, as well as valuable experience, to be lost in the woods any time. Often in a snow storm, even by day, one will come out upon a well-known road and yet find it impossible to tell which way leads to the village. Though he knows that he has travelled it a thousand times, he cannot recognize a feature in it, but it is as strange to him as if it were a road in Siberia. By night, of course, the perplexity is infinitely greater. In our most trivial walks, we are constantly, though unconsciously, steering like pilots by certain well-known beacons and head-lands, and if we go beyond our usual course we still carry in our minds the bearing of some neighboring cape; and not till we are completely lost, or turned round, – for a man lost, – do we appreciate the vastness and strangeness of Nature. Every man has to learn the points of compass again as often as he awakes, whether from sleep or any abstraction. 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.”

“Don't trust children with edge tools. Don't trust man, great God, with more power than he has until he has learned to use that little better. What a hell we should make of the world if we could do what we would!”

“Time is more precious than gold, more precious than diamonds, more precious than oil or any valuable treasures. It is time that we do not have enough of; it is time that causes the war within our hearts, and so we must spend it wisely.”
