David's Time With Peter F. Drucker
2020.2.1
Management books usually deal with managing other people. The subject of this book is managing oneself for effectiveness. That one can truly manage other people is by no means adequately proven. But one can always manage oneself. Indeed, executives who do not manage themselves for effectiveness cannot possibly expect to manage their associates and subordinates. Management is largely by example. Executives who do not know how to make themselves effective in their own job and work set the wrong example.——《The Effective Executive·Preface》
