The choices patients make are not your choices.
All too many chiropractors, especially those who have the habit of caring too much, are afraid that the poor choices that patients make reflect poorly on them. It's not true.
If you’ve withheld the truth then you may be culpable. But that's rarely the case. In fact, it's quite the reverse, often over explaining the implications of dropping out of care too soon and other self-sabotaging patient tendencies.
No, you're working with a fellow human fully equipped with free will and the freedom to accept or reject what you've told them. And while you may assume you're responsible because they've consulted your office and not the office down the street, their health is theirs, not yours. They made the decision to seek care in your office and they're equally free to change their mind or to follow all, or only some of your recommendations.
Lighten up. It's not about you.
