Never complain, never explain. Resist the temptation to defend yourself or make excuses.

The maxim urges disciplined self-control in moments of criticism or misunderstanding. “Never complain” frames grievance as unproductive—energy spent on blame or self-pity is better redirected toward solutions and performance. “Never explain” cautions against reflexive self-justification, which can sound defensive, invite further scrutiny, or signal insecurity. The added sentence clarifies the practical aim: resist the impulse to protect ego through excuses. In a business or leadership setting (where Tracy’s advice typically operates), the quote promotes accountability and composure—letting results, consistency, and calm action speak louder than arguments about intent.
