I have not read this book but I am excited to read it because I can understand what he's saying from one quote "Don't be yourself, be a pizza, everyone loves pizza". What he's trying to say is that he means pizza is about how many friends one can have. If you're a pizza, you have a lot of friends and if your yourself, you may not have that many friends. What it means is that you can be more popular if your a pizza and will be happier.
