I just finished reading this last week. I highly recommend as well. Key take away, understand the habit loop, (cue, response, reward). To change your habit you need to know what the cue is, and watch out for it. When it happens, you need to replace the habit with a difference response that gives the reward. Part of figuring out your cue is looking at People around you, Emotional State, Location, Time, Immediately Preceding Action.
If anyone finds this train of thought interesting, look at literature around Neuro-linguistic programming [0]. As pointed out in the Wikipedia article, this body of work is heavily criticized, and I'll address that, because I think that NLP shouldn't be discarded. The methodicality of the approach outlined in the above comment is somewhat of a central theme in most of NLP, that's what reminded me of NLP. For the purpose of this discussion, I'd sum up NLP as a deep, broad and interesting exploration of the key-take-away from the above comment, that is the trigger-response-reward loop.
It's true that there's a lot to criticize in NLP. What stuck out to me especially was the monetization by R. Bandler and his manner of conversing that is somewhere between being excessively boastful and compulsively lying. However, the Wikipedia article says that the body of work that is NLP was discredited scientifically, which I find preposterous.
I can easily see some practice advocated by a notable NLP practicioner being discredited, but not the whole, because it is too far-reaching. The area covered by NLP makes it pretty much an umbrella keyword for many, many areas of activity of a handful of people. The most controversial of which is probably their revival, reinterpretation and I'd dare say furthering of our understanding of hypnosis, but that's just one thing, and one that I don't find to be their most important contribution.
The basic NLP keywords relevant to this discussion are triggers, mental mapping, anchoring, Meta Model, and then a small host of more advanced concepts that use these building blocks. Their work on the vaguelly named "meta model" alone should be deemed an important contribution, while being minor compared to their work on behavioral therapy.
I can't recommend individual books, since I've sprinted through a bunch of them some years back, their quality somewhat varied, and I had to read some of them to find out that they are repackaged older material, but there are definitely gems out there. The principal authors in the field are John Grinder and Richard Bandler. I would stay away from post-2000 books by Bandler, if I recall correctly. I seem to have found them over-monetizing and a bit distasteful. Bandler also has a lot of video content out there, which again is often distasteful in my opinion.
To sum up on a positive note, I find the literature and work around NLP to be a diamond in the rough, emphasis on diamond.
