Change of any kind requires willingness to change. We go through about 5 stages, precontemplation, contemplation, preparation, action, and maintenance. There should also be a feed back loop to modify the final state to a more favourable state, but that tends to allow creep back to the original issue.
Willingness to change is a state of mind, in fact, the first three are mainly in our head. Until we get to action, it is all in our heads. That is my problem, I think about it and am not strong on the actual doing. Just do it.
