My dear,

The human race has one really effective weapon, and that is laughter.

Because the real enemies we face are pain and sorrow, not each other.

That man on the other side of the planet, he’s not your real enemy. Your true enemy is the sorrow that comes from knowing the world cannot get along. That fellow employee who got the raise instead of you, they’re not your true enemy. Your real enemy is the pain that builds up slowly within you from not quitting and fulfilling your dreams.

Our true enemies are less physical and more abstract. And the only effective weapon we have against them is laughter. It makes the pain and sorrow realize they’re small, abstract, and like us finite; mortal, killable, and mockable.

Falsely yours,
Samuel Langhorne Clemens
