How can we have a rich and fulfilling life? For Peter Drucker, one of the most influential thinkers of modern times, the secret was “living in more than one world” – enjoying a diverse set of interests, activities, acquaintances, and pursuits. Drucker, whose centenary is observed in 2009, was able to do this despite extraordinary demands on his time, and now Bruce Rosenstein shows how the man who transformed organizational management can transform the way you manage your personal and professional life.

An enormously influential business author and consultant, Drucker also wrote extensively on self-development and self-management, but these writings are scattered throughout dozens of books and articles. For the first time, Rosenstein brings these ideas together into a succinct framework that guides you in building a multifaceted life and career. It’s the next best thing to being mentored by Drucker himself.

Rosenstein shares Drucker’s advice for, first, honing in on your core competencies—developing your main talents, clarifying your values, and managing your time. With this firm foundation established, he uses Drucker as both source and example to show how to enrich your life by developing parallel and second careers, making a difference in the lives of others through volunteerism and service, and using teaching and lifelong learning as complementary ways of staying engaged and up to date.

By living in more than one world you gain new insights, see your world from fresh perspectives, access ever-changing sources of inspiration and stimulation. Peter Drucker managed a varied professional life as a writer, educator, and consultant, and was deeply immersed in literature, music, and art. But he wasn’t superhuman. This is a life that can be lived by anybody who has the tools and Bruce Rosenstein provides them in this thoughtful and inspiring book.
