I hadn't thought of it that way, but it satisfies what produced my concern! Mostly for my own sake, not any request of you, here's an expanded take on your rephrasing:

You can't change a habit if it's not really a habit, and you can't evaluate alternatives if you haven't evaluated the default. Don't apply this post's advice if either condition applies to habits in a domain, or if they are very difficult for you to reapply.
