In today's episode, Dr. Killeen talks about a powerful quote from Aristotle: “It is the mark of an educated man to be able to entertain a thought without accepting it.” In a world that pushes us to react quickly and always be “right,” this mindset can be a huge advantage in leadership, dentistry, and everyday life. He shares why great leaders and clinicians stay curious instead of defensive, and how learning to pause, listen, and ask better questions can strengthen communication with patients and teams. Sometimes growth starts not by agreeing with every idea, but by being willing to thoughtfully consider it.
