A powerful piece of advice from Nvidia CEO Jensen Huang encourages a cycle of impact. First, find a way to work on the most crucial projects ("get on the critical path"). Once your involvement becomes a bottleneck, your next job is to enable others and remove yourself ("get off it") to tackle the next challenge.

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.

Success is often attributed not to a relentless personal grind, but to a superpower in attracting and retaining top talent. True scaling and outsized impact come from empowering a great team, embodying the idea that "greatness is in the agency of others."

Ambitious graduates shouldn't join the organization doing the most good in year one, but rather the one that best equips them with skills and networks. This builds "career capital" that prepares them to achieve far greater impact in years 10, 20, and 30 of their careers.

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 transition from a hands-on contributor to a leader is one of the hardest professional shifts. It requires consciously moving away from execution by learning to trust and delegate. This is achieved by hiring talented people and then empowering them to operate, even if it means simply getting out of their way.

When eulogized, a person's career accomplishments are footnotes. The core of their legacy is their character—how they behaved and treated others—and their service. This reality should inform how we prioritize our daily actions, focusing on behavior over status or material success.

Better products are a byproduct of a better team environment. A leader's primary job is not to work on the product, but to cultivate the people and the system they work in—improving their thinking, decision-making, and collaboration.

Lecturer Bill Meehan's former employees volunteered countless unpaid hours for him years later. Their reason: "we could never pay Bill back for what he did for us." This reveals a powerful, lagging indicator of leadership: the voluntary loyalty of former reports.
