“Anger is counterproductive. The flash of rage here, an outburst at the incompetence around us there—this may generate a moment of raw motivation or even a feeling of relief, but we rarely tally up the frustration they cause down the road. Even if we apologize or the good we do outweighs the harm, damage remains—and consequences follow. The person we yelled at is now an enemy. The drawer we broke in a fit is now a constant annoyance. The high blood pressure, the overworked heart, inching us closer to the attack that will put us in the hospital or the grave.”
