Very interesting and a must read book to actually interpret the real meaning of being calm this book has taught me that being calm doesn't means we have to deny our own emontion or show a fake facades to other but to interpret the daily situation differently than we do for example instead of saying "You are wrong and don't know anything" we should say "well, my friend you have an interesting view that differs from my intial interpretation please say more" but I know people won't read this book mainly because of it's cover and judge it because I also did it before reading it.
