My Favorite Mistake: Learning Without Blame in Business and Leadership
My Favorite Mistake is a podcast about learning without blame in business and leadership.
Despite the name, it’s not just my favorite mistake—it’s yours, it’s ours, and it’s what we can all learn from when things don’t go as planned.
Hosted by author and consultant Mark Graban, each episode features honest conversations with leaders, executives, entrepreneurs, and changemakers about a meaningful mistake they made—and what they learned after things went wrong. How they responded. How they improved. How they grew as leaders.
This isn’t a show about failure theater, gotcha moments, or simplistic “lessons learned.” It’s about how real people reflect, improve, and lead better in complex organizations—without scapegoating, shame, or hindsight bias.
What You’ll Hear
• Leadership and management mistakes that reshaped careers, teams, and organizations
• How teams and leaders learn without blaming individuals
• Insights about culture, systems, decision-making, and psychological safety
• Practical lessons drawn from real experience, not abstract theory
Guests come from business, healthcare, technology, sports, entertainment, government, and academia, sharing stories that reveal how learning actually happens.
The Perspective
Mark brings a systems-thinking lens grounded in Lean management, continuous improvement, and psychological safety. The focus is less on who messed up and more on what the system taught us.
Who This Podcast Is For
• Leaders and managers who want to learn from mistakes without blame
• Executives working to build healthier, more resilient cultures
• Professionals who believe improvement starts with reflection, not punishment

Entrepreneur and financial services process improvement leader
Show notes: https://www.markgraban.com/mistake82
My guest for Episode #82 of the My Favorite Mistake podcast is Kyle Kumpf. He has founded a few businesses, has been a consultant, and is currently working in the financial services industry. Kyle has a bachelor's degree in packaging engineering technology from Indiana State University.
Like me, he's been deeply involved in process improvement work (Lean Six Sigma) and his current mission is "ending human suffering as it relates to process in Financial Services."
In this episode, Kyle talks about his "favorite mistake" involving a time when he "disobeyed one of his personal values" -- the customer wanted someONE to blame, and he wrote up an employee. Why did he regret this action and how did he realize it was a mistake? We talk about that, mistakes related to his passion of playing golf, and more.

Show notes and links: https://www.markgraban.com/magill
My guest for this BONUS episode of the My Favorite Mistake podcast is Ron Magill, the communications director for the Miami-Dade Zoological Park and Gardens (or Zoo Miami) — he’s a zoologist and his “favorite mistake” story is one that only a zoologist could tell.
I recently did another bonus episode with five personalities from the Dan Le Batard Show with Stugotz. Ron is a weekly guest each Tuesday on their show. For that original bonus episode, I encouraged people to make donations to the Ron Magill Conservation Endowment, as I did. I hope you'll consider doing the same and it's a great cause.
Today, Ron shares a story about how being young and cocky and careless with a crocodile managed was a "favorite mistake" because it happened for a reason... and it made his life better!
I was able to get this story via the Cameo app and you can also buy a personalized message from him there, if you like.
