Book Review: The Power of Habit

I finished this book a couple of weeks ago. It was interesting, but I can't remember too much about it now, which is why it's only getting 3 stars. I do remember the cue -> action -> reward loop that makes up habit and am half-heartedly applying it to my nail-biting habit. Just knowledge of the cues has already helped me be aware that I'm biting or am about to bite my nails. We'll see what happens. I also plan to implement the habit loop in Zoe's violin practices.
