I also enjoyed that book. I have a friend who has never been taught a lot of basic life skills and this is the book I would recommend to them, because it covers a bit of everything. It explains that eating well is important for our mental health, it explains that one should pay attention to how much of the talking they do in a conversation and make sure others have a chance to talk, etc. It hit on a wide range of good topics and I found it helpful.

I'm a bit surprised how politically charged some people seem to be about this book though. You can see it in the Goodreads reviews, a lot of people giving it one star because it said something they don't like politically. This is not a political book. I don't remember any political commentary from my reading of it, but apparently people have found a sentence here or there that seems to maybe suggest support for a political view they disagree with, so they give it one star. But, it's only a few people doing this and overall this is one of the highest rated books I've ever seen across several sites.
