The Effective Executive by Peter Drucker

1966 People have prioritized since they first had to choose between building a fire for warmth and shaping a spear to bring down ravenous hyenas. In The Effective Executive Peter Drucker codified that instinct into practice. Famously, he decreed that executives must consider not only where to spend their time but also—just as importantly—where not to spend it. Ask business leaders about time management and most will respond with precepts from this book, including: Delegate. Develop action plans. Run efficient meetings. Choose what you can best contribute. (CEOs often phrase this as, “What is it that only I can do?”.)
