No One Gets Bored by Compliments

I received the following card the day after I treated a patient:

I never get tired of receiving thank you cards and notes of appreciation from my patients. I have probably received hundreds of cards like this one over my career and I know that other dentists receive them as well.

What I try to do every day of my professional life is to pursue excellence and try to be one of the best dentists ever. Any dentist that does not try to be the best has become accepting of mediocrity. Most important to me is that many of my patients take notice of our efforts to deliver excellence and be as good as we could possible be.

Why would any patient want to go to a physician or dentist that does not strive to be the best?
