Good ideas, and I can see the point in what you are saying. Rather than obsessing over not smoking and constantly thinking about it, people should just stop smoking and forget it. I do like to check and see how much money I've saved from time to time.
"people should just stop smoking and forget it."
Stopping smoking is difficult, but by directing that mental energy into reinforcing the idea that " I don't smoke" instead of the countless resisting of impulses such as desiring a smoke when you wake, or are going to bed, or during a bathroom break, or after a meal, or after sex, or when trying to kill a block of time, or when you walk into a room.
It is easier to have one thought to focus on, " I am not a smoker, so it means nothing to me", I think this also shortens the worst initial withdrawal period, and makes it easier to not backslide (since there is nothing to go back to).
