Are you the best doctor at doing what you do?

You might be, but you might not be (and probably aren't).

...but every patient that you have treated has decided that you were the best doctor to treat them, so what have they based that decision on?

Think about why patients choose a doctor and you will realise that there is a lot more to it than how good a doctor they are.

If you can work on these other areas of your practice, then you will help you patients to make the decision to choose you.
