I agree.

Well, I had a moment of clarity that motivated me. However, this forum -- success stories in particular, and recipes, and journal, and blogs -- etc. helped keep that up long enough for me to lose enough weight to feel good enough that I was better able to pull a few habits more into my ordinary life.

Or as you say your comfort zone, so that "motivation" is not really required; it needs to be 'just another day' and then the process works on its own. Then motivation or not, 'willpower' isn't needed, only 'habit'.
