760. The Pebble in Your Shoe

In this episode, Dr. Killeen reflects on a favorite Muhammad Ali quote: “It isn’t the mountains ahead to climb that wear you out; it’s the pebble in your shoe,” and why it matters so much in dentistry, leadership, and life. Big goals and “mountains” get our attention, but it’s often the small, nagging issues we tolerate that quietly wear us down. Dr. Killeen talks about identifying those pebbles—habits, mindsets, or situations that drain energy—and why addressing them can make everything else feel lighter. A simple reminder that progress often starts with fixing the small stuff first.
