Early leadership mistakes often stem from a perceived need to have all the answers. A more powerful approach is to express confidence in the mission while openly asking your team for feedback on how you can improve as a leader to better serve them and the company.

Early career advice focuses on fixing weaknesses. However, experienced leaders should shift their focus. While weaknesses must be mitigated so they don't become a liability, true effectiveness comes from understanding, amplifying, and deploying your core strengths, which is what ultimately makes you a great leader.

New leaders often fail because they continue to operate with an individual contributor mindset. Success shifts from personal problem-solving ("soloist") to orchestrating the success of others ("conductor"). This requires a fundamental change in self-perception and approach, not just learning new skills.

Treat mentors as a collection of traits, not a monolithic influence. Actively adopt the qualities you admire while consciously rejecting the ones that don't align with your goals. A person can be a great role model for one area of life but a poor one for another.

Transitioning from a top-performing rep requires a mindset shift from doing to enabling. A new leader's role is not to teach their specific 'Michael Jordan' method, but to align company and personal goals, then focus on removing obstacles for each team member's unique path to success.

The "treat others as you want to be treated" mantra fails in leadership because individuals have different motivations and work styles. Effective leaders adapt their approach, recognizing that their preferred hands-off style might not work for someone who needs more direct guidance.

There are no universal leadership traits; successful leaders can be introverts, extroverts, planners, or chaotic. What they share is the ability to make others feel that following them will lead to a better tomorrow. This emotional response is what creates followers, not a specific checklist of skills.

No single teacher or mentor is perfect. A more effective approach is to identify specific, desirable qualities in various people—such as an investor's rationality or a leader's compassion—and focus on learning how to embody those particular traits, rather than idealizing the entire person.

What made you a great PM will not make you a great director. The journey into leadership is a process of being humbled, recognizing your worldview is incomplete, and adapting your thinking. If you are not humble enough to change your mind, you will struggle to grow in your career.
