Peter F. Drucker · 1999 · career self-knowledge
Managing Oneself
Drucker turns career growth inward: know how you perform, where you belong, what you contribute, and which relationships require explicit expectations.
Core idea.
You cannot manage a career well with generic excellence. Drucker asks for feedback, operating preferences, values, and contribution because effectiveness depends on fit as much as effort.
