📘 Book Summary

Marshall Goldsmith’s book is a blunt reminder that the biggest obstacles for successful leaders aren’t skill gaps—they’re behavioral blind spots. Goldsmith lays out the twenty common habits that undermine high achievers: defensiveness, needing to win too much, refusing to apologize, clinging to old methods, or simply ignoring feedback. His point is direct: the behaviors that earned you early success often become liabilities as the stakes rise. Advancement requires self-awareness, humility, and the courage to change the habits that no longer serve you—especially the ones you’re most attached to. The book teaches leaders to confront their own arrogance, listen more than they talk, and deliberately replace ego-driven actions with growth-driven ones.

🔑 Key Executive Takeaway

If you want to reach the next level, you must be willing to shed the behaviors that built the last one. The leaders who stagnate are the ones who refuse to evolve. The ones who rise are those who face their blind spots head-on and let go of the habits that no longer produce results.

THIS RULE HELPS YOU WITH 🧭

  • Breaking autopilot routines that no longer yield results
  • Identifying legacy habits or leadership styles that stall progress
  • Letting go of ego-driven behaviors that were once rewarded
  • Creating space for better decisions by eliminating wasteful actions
  • Evolving as a leader by aligning your behavior with your future, not your past

🔍 ASK THE RIGHT QUESTIONS

“Progress starts with asking better questions. Use this section and these prompts throughout The Institute to challenge assumptions, surface blind spots, and drive clearer thinking.”


These questions are designed to reveal what needs pruning in your leadership, business strategy, or team culture. Each includes an example to ground the thinking:

What am I still doing just because it used to work? (Inner Dialogue🧠)


→ Example: You’re still personally approving every marketing campaign, even though your team has outgrown the need for that level of oversight.


Where am I avoiding change because I’m afraid of losing control or comfort? (Inner Dialogue🧠)

→ Example: Refusing to delegate key client relationships because you’re attached to being the face of the business.


What behaviors are rewarded in this organization that actually hold us back?


→ Example: Celebrating constant busyness instead of real outcomes keeps people chasing noise instead of results.


Who on my team—or in my peer group—is holding on to yesterday’s playbook? Have I called it out?


→ Example: A longtime sales leader still pushing cold calls instead of adapting to inbound strategies, and no one is challenging it.


Many leaders rise by doing certain things very well—then fall by continuing to do those same things for too long. This month, challenge your group to surface and name what’s no longer serving them.

Lead-In:
The hardest things to let go of are often the ones that got us applause in the past. But the market doesn’t care what used to work. It rewards what works now. So—what needs to go?

What’s one behavior, process, or decision-making habit that once worked for you or your business—but no longer does? Why is it still hanging around?
