It's common knowledge that single women are lonely, desperate for a partner, and envious of every couple they see. Spinsters struggle later in life, never feel fulfilled, and would just love for you to set them up with your neighbor’s nephew. But, what if society’s ideas about single people—who, by the way, comprise half of the adult population—are wrong? Bella DePaulo PhD challenges the notion that single life is something people settle for, and shows that for millions, in every part of the world, being unpartnered is the key to their most joyful, fulfilling, authentic, and psychologically rich life. Drawing on more than three decades of social science research, and her own experience as a 70-year-old woman happily single her entire life, DePaulo—whose TEDx Talk on the topic has more than 1.7 million views—paints a bold and groundbreaking picture of the myriad benefits of investing in your single life. Bella DePaulo PhD ( Harvard University) has always been single and always will be. The Atlantic calls her “America’s foremost thinker and writer on the single experience.”
