Feedback on Offer Sought

I’m super excited about an initial program (not a signature program) that I am creating and looking for feedback on how to position it.
It will be a 30 day stair-step “challenge” that is designed to help break bad habits and create positive ones. I’m not sure whether to focus in the naming/marketing on changing the negative or building the positive. I feel like people respond more to solving problems but I also know that creating lasting change require positive thoughts.

So names I’ve come up with are “30-Day Habit Change” “30-Day Habit Correction” “30-Day Habit Builder”
Don’t know if this appropriate to ask here but I’m asking anyway.
I’ll take any feedback you’ve got. 🙂
