In Curveball, Zito transparently portrays how he lived years being guided by an entitled and insatiable ego. He shares what it felt like to live the “dream life” full of money and fame, yet feel so empty inside because of the way he had attached his identity as a person to his performance as a player. Zito shares how destructive it was to take his career so seriously and how his inability to let go of his need to control led to his demise, both in baseball and in life.
