This quote is a concise mnemonic about the opportunity cost of anger. It reframes the familiar saying "every minute you are angry, you lose sixty seconds of happiness" in plain arithmetic: anger and happiness are mutually exclusive, and time spent on one is time taken from the other. The sentiment echoes Stoic and Buddhist teachings that anger is a self-inflicted wound, and the playful tautology ("sixty seconds" being exactly one minute) drives the point home. It resonates because it turns a vague feeling into a measurable loss, encouraging emotional discipline.
