Habits, like most other things, can be a help, or a hindrance, and are loved by nature because they are so energy efficient. They function automatically, bypassing the need to think, assess, decide, etc. This is lovely stuff, unless it’s a negative habit. Then what?
If you think in terms of, “Problem, Reaction, Solution”, where the “Problem” is the Stimulus, the “Reaction” is the Habit, and the “Solution” is the Pay-off, you’ll realise that the “Habit” is not the “Problem”.
People struggle to alter a Habit when, what they really need is, a no-nonsense approach to locate and un-hook the real cause of the trouble.
