This book is incredibly repetitive and the ‘let them’ theory could have been explained in just a few pages. It’s exactly what you’d expect it to mean - when someone bothers you, let them. I don’t need to read a full book about it. While I have nothing against Mel, I’m surprised by the overwhelmingly positive reviews. It hasn’t brought any new insight to me, it’s just another way of saying the usual advice that has been used over and over about not letting others get to you. I’m not sure I’ll even finish it.
