While acknowledging the benefit of having mentors, Herb Wagner has found that the process of being a mentor is even more educational. Teaching and guiding others forces a deeper understanding of one's own principles and provides fresh perspectives from the next generation, offering greater personal and professional growth.

The best test of knowledge is the ability to teach it. By having employees explain a new AI tool or workflow to their peers, they are forced to solidify their own understanding and identify knowledge gaps. This process turns passive learning into active expertise.

Mentoring is not just altruistic; it's a powerful tool for self-improvement. When mentees apply a senior PM's frameworks and encounter challenges, it forces the mentor to refine their models, plug gaps, and confirm which patterns are truly repeatable. It's a feedback loop for your own expertise.

Seek mentors who are only one or two years ahead in your career path (e.g., a manager mentoring a coordinator). Their experience is more recent and relevant to your current challenges than that of a CMO who was in your role a decade ago in a different marketing landscape.

Maximize the value of senior experts by pairing them with junior colleagues in key meetings. The senior brings deep experience, while the junior's role is twofold: to absorb knowledge like a sponge and to act as a real-time translator, helping to course-correct the senior's communication to land with younger audiences.

A manager is not a mentor. Instead of depending on a single, formal mentor within their reporting structure, aspiring leaders should cultivate a personal 'board' of two or three trusted advisors. This external network provides diverse, on-demand input for specific business situations that fall outside a leader's direct experience or comfort zone.

Mentoring's value increases when done outside your direct org. It becomes a two-way street: you learn about other parts of the business, and you can plant seeds of influence and better engineering practices that can grow and spread organically throughout the company.

Many leaders, particularly in technical fields, mistakenly believe their role is to provide all the answers. This approach disempowers teams and creates a bottleneck. Shifting from advising to coaching unlocks a team's problem-solving potential and allows leaders to scale their impact.

Mentoring provides leaders with a grounded view of challenges across the organization. This fosters empathy and a "systems thinking" mindset, reminding leaders that sustainable impact comes not just from building products, but from enabling the people who build them and creating space for them to grow.
