“Men and boys are learning all kinds of trades but how to make men of themselves. They learn to make houses; but they are not so well housed, they are not so contented in their houses, as the woodchucks in their holes. What is the use of a house if you haven’t got a tolerable planet to put it on? — If you cannot tolerate the planet that it is on? Grade the ground first. If a man believes and expects great things of himself, it makes no odds where you put him, or what you show him … he will be surrounded by grandeur. He is in the condition of a healthy and hungry man, who says to himself, — How sweet this crust is!”
Henry David Thoreau, Letter to Harrison Blake 20 May 1860; emphasis added, published in Familiar Letters 1865.
