Ben Horowitz, a leading venture capitalist, modern management expert, and New York Times bestselling author combines lessons both from history and modern organisational practice with practical and often surprising advice to help us build cultures that can weather both good and bad times. The times and circumstances in which people were raised often shape them - yet a few leaders have managed to shape their times. In this follow-up to the bestselling business classic The Hard Thing About Hard Things, Ben Horowitz turns his attention to a question crucial to every organisation: How do you create and sustain the culture you want? This book is a journey through cultures ancient to modern, spotlighting models of leadership and culture-building from the samurai to prison gangs. Along the way, it answers fundamental questions: Who are we? How do people talk about us when we're not around? How do we treat our customers? Can we be trusted? Because who you are is not the values you list on the wall. It's not what you say in a company-wide meeting. It's not your marketing campaign. It's not even what you believe. Who you are is what you do. This book will help you do the things needed to become the kind of leader you want to be - and others want to follow.
