S, when we feel unhappy again (cue), rather than eat snacks, we culd listen t sme f ur favurite music instead (rutine), which will make us feel relaxed (reward). Aside frm changing bad habits, we can als use the habit cycle t create gd habits. Fr example, when we cme t an escalatr(cue), ur nrmal rutine is t ride it, but we culd change this rutine int smething mre psitive by taking the stairs instead.
