We’ve all seen it happen. The top salesperson becomes the Sales Manager. The most brilliant coder becomes the Lead Engineer.

Then, something shifts. The very skills that earned them the promotion—technical mastery, speed, and individual output—aren’t the skills they need to lead. This is the Peter Principle in action: the phenomenon where people are promoted based on their success in a previous role until they reach a position that requires a completely different set of strengths. But here is the truth we don’t talk about enough: Leadership isn’t a trophy for past performance. It is a new craft that must be carved and forged through experience.

If you’ve recently made the jump from “doer” to “leader,” here is why vulnerability and incremental growth are your two most powerful tools for closing that gap.

1. The Myth of the “Bulletproof” Leader

Many new managers feel they need to wear a mask of absolute certainty. They think, “If I admit I’m still learning the ropes of management, they’ll think I wasn’t ready for this role.”

In reality, that mask creates a wall.

Vulnerability is a bridge. When you are honest about the fact that you are transitioning from “doing” to “leading,” you create psychological safety. You give your team permission to be honest about their own challenges, which leads to fewer hidden mistakes and faster problem-solving.

2. Using Vulnerability as a Strengthening Tool

Vulnerability isn’t about oversharing personal problems; it’s about intellectual honesty. * The “I’m Learning” Approach: If a team member is an expert in a niche you haven’t mastered, ask them to teach you. You gain their respect by valuing their expertise rather than pretending to be the smartest person in the room.

  • The “Extreme Ownership” Move: When you make a bad call, own it immediately. A leader who admits a mistake is a leader who can be trusted.

3. The Power of Incremental Improvement

You didn’t become a top performer overnight, and you won’t become a great leader overnight either. Leadership is a foundation built brick by brick.

Instead of trying to be the perfect manager in Week 1, focus on 1% gains:

  • This week, focus on active listening in 1-on-1s.
  • Next week, focus on providing more specific, actionable feedback.
  • The following week, practice delegating a task you’d normally do yourself.

The Bottom Line

If you feel a bit “out of your depth” as a new manager, congratulations—you’re likely just experiencing the natural shift from technical expert to people leader. You aren’t failing; you’re forging. Lean into the discomfort. Ask for feedback. Be human. The best leaders aren’t the ones who have all the answers; they are the ones who aren’t afraid to go find them with their team.
