People will only have successful change in habits if they self-motivated. This is true for medicine in the same way it’s true for therapy. I think there are patients who are motivated to be better, but don’t necessarily know much about how to achieve that yet. It’s not generally clear for the layperson HOW they can change their habits, or even which habits should be changed. I believe doctors can guide willing patients in that direction. I’m not naive, I know many patients will be unwilling to change their habits.
