Drucker's famous sayings are as follows:

1. The first sign of a company's decline is that it loses its attraction to capable and ambitious talents.

2. Management is not about knowledge, but about doing.

3. I would never promote someone to the top job who never makes mistakes, especially big mistakes.

4. Management is a practice, its essence lies not in "knowledge" but in "action"; its verification does not lie in logic, but in results; its only authority is achievement.

5. The manager’s task is not to change people, but to use everyone’s talents.

6. We need to look at what is a “proper decision” rather than what “people can understand”.

7. Effective managers need the impact of decision-making, not decision-making skills; they need good decisions, not clever decisions.

8. An enterprise is not defined by its name, articles of association and company regulations, but by its mission. Only when an enterprise has clear tasks and goals can it set clear and realistic corporate goals.

9. People who achieve something start from the most important things. And, do one thing at a time.

10. As a leader, he has only one choice, which is to lead or to mislead.
