Not necessarily. Sometimes, it is unconscious where a part of us is not willing (or scared, uncomfortable etc.) to do what needs to be done in order to get better.

After all, there is no physical force preventing you from doing the stuff you need to do yet there is a resistance (mental, emotional...) that is preventing you from taking the steps you need to take in order to get better.

That is an interesting question and makes one think of underlying motivations re why we remain stuck.
