""When Perfect Isn't Good Enough" is an excellent source for people looking to adjust their standards and expectations and, by so doing, increase the joy in their lives. It is easy to read, filled with solid advice, and based on the best scientific research. Unlike most other self-help books, the many exercises suggested by the authors provide the reader with the tools to put these words into action. Antony and Swinson have produced a thorough and systemic manual to lead the perfectionist out of the misery of depression, anger, worry, and social anxiety, and into the promised land of realistic self-evaluation, self-esteem, and positive interpersonal relations.
