Overview

Deliberate self-challenge — seeking steep learning curves and unfamiliar problems — keeps leaders growing beyond plateaus. Admitting "I don't know" to a team is not a weakness but the distinguishing trait of great leaders over good ones.

Key takeaways

  • Deliberately choosing unfamiliar challenges after reaching a plateau restarts growth without destroying what you built.
  • Telling your team you don't know how to do something recreates the energy of early-career learning.
  • Leaders who admit uncertainty make it safe for others to contribute, turning the unknown into a shared problem.
  • Fear of saying "I don't know" or "I made a mistake" is common, but acting despite that fear defines great leadership.
  • The gap between good leaders and great leaders is the willingness to say: I was wrong, I need help.

Worth quoting

  • "What distinguishes the great leaders from the good leaders is their ability to say, I made a mistake, I don't know, I need help."
  • "Try something new that you have to admit to your team, I have no idea how to do this."
  • "The thrill of our early careers was that."
