What does it mean to be "clutch"? In his new book Clutch: Why Some People Excel Under Pressure and Others Don’t, author Paul Sullivan defines "clutch" as the ability to do what you can do normally under immense pressure. Drawing on examples from sports, business, law, the military, and show business, he identifies the traits of those who are consistently able to overcome extreme pressure and beat the toughest odds. He also looks at what causes some people to choke under pressure. According to Sullivan, clutch performance does not stem from an innate ability but is a learned skill that anyone can develop. He provides practical advice on how one can excel in difficult situations in everyday life, both personally and professionally.
