683. You're Not the Same Person Anymore

Dr. Killeen reflects on a quote from Heraclitus about how nothing stays the same, including us. The systems, conversations, and habits we revisit over time often produce different results because we’ve grown, learned, and changed along the way. He shares why this mindset matters so much in dentistry and leadership. Sometimes a process or idea that “didn’t work before” deserves another look, not because the system changed, but because the people using it have evolved. Growth is not always about chasing something new. Sometimes it’s about returning to familiar things with a better perspective.
