The Dangers of Closed-Minded Leadership

Great founders hold strong opinions, but they also know when to change their minds.

In this episode, Ninety Founder & CEO Mark Abbott and Brand Strategist Cole Abbott explore how high-performing leaders evolve their thinking, challenge their biases, and refine their decision-making over time. They break down the balance between conviction and adaptability — and why staying too rigid can hold you and your company back.

What you’ll learn:

• Why strong opinions should be earned, not assumed
• How to challenge your own biases and avoid blind spots
• The role of ego development in leadership
• How to think in frameworks that allow for growth and change
