Kelly McGonigal has realized through many years of research that most people hold incorrect perceptions about willpower, which causes our self-control to falter and thus sabotages our success. Based on the latest research from various industries and many years of working experience, Kelly begins with talking about multiple factors that lead to a loss of control and guides readers towards a better understanding of willpower. She does this by telling people how to break old habits, overcome procrastination, and manage stress, as well as by presenting practical strategies for training willpower.
