Dr. Killeen shares a simple but important reminder that confidence is not built only through success. While things going well help build competence, the moments that do not go as planned are often where something deeper is developed. In dentistry, challenges are inevitable. Procedures get complicated, conversations miss the mark, and systems break down. But working through those moments builds resilience and reinforces the belief that you can handle difficulty when it shows up again. Growth comes from both sides of the equation. Success builds skill, and struggle builds strength. Over time, it is the combination of both that creates lasting confidence.
