You Can't Afford the Luxury of a Negative Thought
A self-help book by Peter McWilliams, written with John-Roger, arguing that dwelling on negative thoughts is a cost most people cannot afford, for their health, happiness, and relationships. It mixes brief chapters, quotations, and exercises encouraging readers to notice and release habitual negativity. The tone is warm, aphoristic, and quick to read, with plenty of white space and pull quotes. For a book club it is a light, motivational read that tends to spark personal reflection more than analysis.
