In general I think most people trying to intervene on most other people's behavior are doing it at much too low a level (in the sense of low-level programming languages).

In my own personal growth experience most major changes to my own behavior came from tweaking much deeper things like how fundamentally safe / loved / cared for I feel, training emotional processing / regulation, etc. Not by e.g. exerting willpower to do different stuff.
I guess it's much easier in the moment or simpler to convey "stop doing that particular behaviour".
