Peter Drucker 
The Daily Drucker [PDF ebook] 

A powerful new learning tool for the ambitious, self-directed manager, entrepreneur, or business person today,
The Daily Drucker distils the essence of management guru Peter F. Drucker”s teachings in an easy-to-access, daily calendar format. It presents in organized form: a key statement of Drucker’s, followed by a few lines of comment and explanation, with topics ranging across a great many fields of his work: management, business and the world economy; a changing society; innovation and entrepreneurship; decision-making; the changing workforce and the non-profit and their management. However, the most important part of this book are the blank halves of its pages. They are what the readers will contribute, their actions, decisions and the results of these decisions.
There are 366 readings, each addressing a major topic, one for every day of the year. Each reading starts with a topic and a “Drucker Proverb” such as “Know Thy Time”, capturing the essence of the topic. Then there is a teaching taken directly from the works of Peter Drucker. Next comes the action step, where you are asked to “Think on” the teaching and apply it to yourself and your organization.
