Successful individuals receive endless mentorship requests. Instead of helping everyone or no one, they should focus their limited time on 'multipliers'—people whose position or potential allows them to influence and develop many others. This strategy scales a leader's wisdom and impact.

Veteran high-achievers often become desensitized to success, feeling anxiety about the next goal rather than satisfaction. True fulfillment can be rediscovered by mentoring junior colleagues and vicariously experiencing the elation of their 'first win,' which can reignite a leader's own passion.

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.

Ultimate career success for a leader is not measured by profits or personal accolades but by the growth and achievements of the team members they've coached and empowered. By focusing on building up others, a leader creates a cascading effect of success throughout the organization, which is the most meaningful and lasting impact.

Effective leadership prioritizes people development ('who you impact') over task completion ('what you do'). This philosophy frames a leader's primary role as a mentor and coach who empowers their team to grow. This focus on human impact is more fulfilling and ultimately drives superior business outcomes through a confident, motivated team.

The initial goal of building a company that endures can be misplaced. A more meaningful and lasting legacy is created through the people you train and empower. The corporate entity may fade, but the skills and values instilled in your team will ripple outwards for decades through their own ventures and leadership.

Busy, successful people mentor others because they find joy in watching that person grow. Mentees must show they are applying the advice and getting results. This demonstrates a return on the mentor's time and emotional investment, ensuring their continued engagement.

Mentoring isn't just about imparting wisdom; it's a "selfish" act of learning from the younger generation. Mentees offer valuable insights into modern approaches to productivity, work-life balance, and leveraging new technologies. They are more focused on output over hours and aren't guilty about taking vacations, providing a fresh perspective for senior professionals.

An oncology leader measures his contribution not by personal discoveries, but by his ability to coach and mentor the next generation. He believes the greatest legacy is enabling others to become even more brilliant and successful, effectively passing the baton to smarter people.
