I am struck by the fact that the more slowly trees grow at first, the sounder they are at the core, and I think that the same is true of human beings.
Henry David ThoreauThe murmurs of many a famous river on the other side of the globe reach even to us here, as to more distant dwellers on its banks;many a poet's stream, floating the helms and shields of heroes on its bosom.
Henry David ThoreauWe say justly that the weak person is flat, for, like all flat substances, he does not stand in the direction of his strength, that is, on his edge, but affords a convenient surface to put upon. He slides all the way through life.... But the brave man is a perfect sphere, which cannot fall on its flat side and is equally strong every way.
Henry David Thoreau
