I easily correct bad habits that are keeping me from staying perfectly healed.

Habits are rarely about the thing itself. The cigarette was often the five minutes outside on your own. The glass in the evening was the line between the working day and the rest of it.

Which is why deletion tends not to work. Take away the object and the need it was serving is still standing there at six o'clock with nothing to do.

Correction, done well, is usually substitution. Something else that occupies the same five minutes and marks the same boundary. Less impressive than willpower, and considerably more durable.
