Effectiveness is not a gift, it's a habit
Drucker opens the book with a provocation: effectiveness has nothing to do with intelligence, charisma, or a degree. He has seen brilliant people deliver little, and ordinary people with no standout résumé produce solid results month after month. The difference was never raw talent. It was the set of habits a person practiced until they became routine.
This changes the whole conversation: if effectiveness were a gift, only those born with a knack for leadership could develop it. Since it's a habit, any employee, freelancer, or corner-bar owner can learn to practice it, the same way you learn to drive or cook, through repetition and course correction.
The book asks for a bit of self-discipline right from the start: a habit isn't installed by watching a motivational talk. It's installed by testing a new behavior for weeks until it stops requiring conscious effort. It's workbench labor, not a Sunday epiphany.
