In Quit, author Annie Duke argues that our inability to quit is holding us back in both our personal and professional lives. Drawing on examples from elite athletes, business leaders, and entertainers, she teaches readers how to determine when it's time to quit and provides strategies for making better decisions, such as thinking in expected value and establishing "quitting contracts." She also discusses the psychological and societal forces that work against good quitting behavior, such as escalation commitment and status quo bias, and offers best practices for increasing flexibility in goal-setting and anticipating future options. The goal of the book is to help readers master the skill of quitting in order to make the best next move in their lives.
