The phrase "Comparison is the thief of joy" is most often attributed to Theodore Roosevelt, the 26th president of the United States. However, there is no solid evidence that Roosevelt actually said or wrote this exact phrase. The quote's first publication with the exact wording appears to be by Dr. Ray Cummings. Despite the uncertainty of its precise origin, the phrase is widely linked to Roosevelt and has become a popular saying about how comparing oneself to others can diminish happiness and satisfaction.
