I recently finished 'Aventures of a Bystander' by Peter Drucker. It's billed as his memoirs, and it is an interesting read about a man who led an interesting life. It not all self centered, he spends a great deal of time talking about other people and does detailed analysis regarding how the people he profiled developed. Many of the persons he covers were famous, rich, or both.
I definitely found myself wondering if the world Peter Drucker lived in still exists. Could a person create a life like he did? Perhaps, but it's so far over my head that it seems impossible.
