I read this book shortly after it was published in 1990. At the time, I was migrating from roles that were more managerially focused to roles that were more dependent on the advancement of my leadership skills. The subtitle on this book, “How Leadership Differs From Management,” spoke to me and the book itself helped me sort through this issue in a balanced and constructive way. Clearly, to be highly effective, one needs to be proficient as both a manager and a leader and this book stimulated my journey on both dimensions. If you choose to read nothing else in this book, read page 139 – it advances a helpful framework for wrestling with this issue.

John shared his ideas with our global leadership team and I found his thinking quite clear, clean and relevant.
