There is not one kind of food for all men. You must and you will feed those faculties which you exercise. The laborer whose body is weary does not require the same food with the scholar whose brain is weary.
Henry David ThoreauIt is something to be able to paint a particular picture, or to carve a statue, and so to make a few objects beautiful; but it is far more glorious to carve and paint the very atmosphere and medium through which we look, which morally we can do. To affect the quality of the day, that is the highest of arts.
Henry David Thoreau
