" And another nice thing about war—not that anything about war is nice, I guess—is that while it’s going on and you’re in it, you never worry about doing the right thing. See? Up there, fighting and all, you couldn’t be righter. You could of been a heller at home and made a lot of people unhappy and all, and been a dumb, mean bastard, but you’re king over there—king to everybody, and especially to yourself. This above all, be true to yourself, and you can’t be false to anybody else, and that’s it—in a hole, being shot at and shooting back. "
― Kurt Vonnegut Jr. , Player Piano
