Best book on game design ever!

Most books I’ve seen talking about game design are super expensive ($50+) and although often had some interesting ideas about game designers, none have even gone into the philosophy so deeply before.
I highly recommend this book to anyone looking to get in the game industry or is new in the game industry and struggling. Actually, like the book description also says, anyone struggling in life would probably have a few things to learn from this book too!
Great buy!!!
