The main point of this book is that if you want to have friends and be successful, you should be nice not mean. It sounds so obvious and I thought I was doing it, but now I realize all the mean things that I've done and still do to people when I don't get along with them. As I've read this book (and I'll work hard to do this from now on) I've tried to think more about the other person's perspective when I disagree with them and it helps so much. I've already noticed a change in the way I interact with people. This is a great book. I highly recommend it to anyone who wants to get along with other people. It's a very humbling yet empowering book.
