“At least once every human should have to run for his life, to teach him that milk does not come from supermarkets, that safety does not come from policemen, that 'news' is not something that happens to other people. He might learn how his ancestors lived and that he himself is no different--in the crunch his life depends on his agility, alertness, and personal resourcefulness.”
― Robert A. Heinlein

“I've found out why people laugh. They laugh because it hurts so much . . . because it's the only thing that'll make it stop hurting.”
― Robert A. Heinlein, Stranger in a Strange Land

“I never do anything I don't want to do. Nor does anyone, but in my case I am always aware of it.”
― Robert A. Heinlein, Stranger in a Strange Land

“Violence, naked force, has settled more issues in history than has any other factor.”
― Robert A. Heinlein, Starship Troopers
