In 'What You Do Is Who You Are,' Ben Horowitz, celebrated venture capitalist and management expert, delves into the essence of organizational culture through the lens of historical and modern leadership. Drawing parallels between leaders as diverse as Haitian revolutionary Toussaint Louverture and corporate giants like Reed Hastings of Netflix, Horowitz illustrates how culture shapes decision-making. He explores how leaders like the Samurai, Genghis Khan, and Shaka Senghor have left indelible marks on their societies by instilling purposeful cultural values. This journey crosses temporal boundaries to elaborate on how to create and maintain an organizational culture that truly reflects who you are as a leader—because in the end, the actions you take define the culture of your company.
