As your years at the company stack up, doesn’t your shoulder feel heavier? You’re stuck in a “sandwich” position—juniors pushing from below and seniors pressing for results from above. You want to be a cool mentor, but in the heat of a busy workday, the words “I wish they’d just handle it on their own” often crawl up to your throat.
I also used to think teaching juniors was a “waste of time” that interfered with my own work. However, after reading “Good Mentor” (often referred to in John Maxwell’s leadership series like Mentoring 101), my perspective shifted entirely. This book doesn’t just tell you to be a “kind senior.” Instead, it coldly analyzes and persuades you that growing others is actually the best way to increase your own market value and make yourself irreplaceable in an organization.
Core Concept: Leadership is Completed Through “Multiplication”
The single most important viewpoint in this book is: “A true leader does not create followers, but creates more leaders.” The author defines mentoring not as simple advice, but as an investment. When you unreservedly pass on your know-how to create someone even better than yourself, you finally gain the authority and freedom to move to a higher level of work.
Ultimately, a “Good Mentor” is both an altruistic person who helps others succeed and a brilliant strategist who knows how to infinitely expand their own influence. While performance achieved alone has a clear limit, the performance achieved by the mentees you’ve raised becomes your portfolio. The book logically proves this fact.
Connecting to Life: The Quality of Relationships Defines Your Salary Ceiling
They say “relationships” are harder than “work” in office life, but paradoxically, how you manage those relationships determines your economic value. There are many skilled “lone wolf” managers, but those who can pull out the potential of team members to grow the entire team’s pie are rare and valuable.
Mentoring isn’t just “playing the nice senior.” In the process of helping someone grow, your communication skills, empathy, and strategic thinking develop exponentially. These abilities are assets that sell at a much higher price than technical proficiency as you advance in your career. When you understand the system of growing people rather than just chasing money, your career will enter a trajectory of “exponential growth” rather than “linear growth.”
My Interpretation: The Fear of “Unreserved Sharing”
To be honest, I hesitated at the part where the book claims, “Share all your know-how without reservation.” The workplace is a battlefield, and I felt I had to protect my own plate. My instinctive fear was: “What if I share my secret weapon and the junior takes my spot?”
But upon reflection, I realized that while I was hiding my knowledge, I was becoming “stagnant water,” stuck at that same knowledge level. I realized that only by passing my “present” to a junior can I move toward my “future.” Accepting the paradox—that you learn the most while teaching and that a mentor with great mentees never becomes obsolete—finally unlocked my heart.
Action List: Things to Do in the Office Today
- Say “You’re doing great”: Indifference is scarier than a lack of teaching. Pick one tiny detail your junior did well today and give them a specific compliment.
- Answer with a Question: When a junior comes for an answer, don’t give it immediately. Ask, “What choice would you make in this situation?” and give them a chance to think.
- Share Your Mistakes: Don’t pretend to be perfect. Lightly share a mistake you made in the past and the lesson you learned. Psychological safety is the beginning of mentoring.
Closing: Have You Ever Been Someone’s “North Star”?
John Maxwell says becoming a great mentor isn’t a matter of skill, but a choice. It’s the decision to return the help you received to someone else and grow yourself in the process.
Have you sincerely rejoiced in someone’s growth while sharing your know-how today? When you eventually leave this company, how many people will remember you as the “turning point” of their lives?
