You've probably heard, "If you keep doing what you've always done, you'll keep getting what you've always got." To that add: until you don't. That's where many chiropractors find themselves. What used to work doesn't.
Now what?
Show up curious. You need the truth. Ask your current patients more questions.
"Why did you choose chiropractic to address this issue?" (Clue: it wasn't to restore a lordotic curve!)
"What do you hope to do better or enjoy more when you regain your health?" (Clue: it isn't so they can rave about their chiropractor!)
"If this were your practice how would introduce more people to chiropractic?" (Clue: Ignore every suggestion involving advertising.)
When times change, you must also change. For the moment, forget about making the right choice. Just choose! The danger is in freezing and not taking action. (Which is most certainly the wrong choice!) Choose, and then make it the right choice.
