In addition, I haven't seen the third step in the "Cue -> Habit -> Reward" cycle mentioned yet. While the Reward may be the lingering endorphin rush from a hard workout or the feeling of accomplishment after finishing a chore, the author also suggests a simple, pleasurable behavior after the task that you're trying to make a habit of (like a small piece of chocolate immediately after a run or allowing yourself a few shameless minutes of cat videos after a focused study session). The idea is to allow your mind to associate the pleasure response with the habit each time it encounters the cue.
