The value of a mentorship isn’t just for your protégé — answering questions that younger people ask can help you clarify your own thinking. As you talk about what it means to be an executive, you’ll get a second chance to learn why you do things the way you do and what assumptions drive your actions. Your answers will force you to be explicit about the embedded rules and mental models you’ve been using to make decisions, reinforcing what you now know. This second-time-around learning turns good managers into great ones. While you impart new knowledge and perspectives to your mentees, you will also gain deeper insight into your own work.
