Punch in the face
All of David's books are true eye openers, or a real punch-in-the-face for most. They provide the context to the bigger picture most overlook or are completely oblivious to. Every single book has been a pleasure to read, they're all packed full of very useful knowledge. I'm amazed still at just how many things I've learned. I highly suggest this book to anyone and everyone. David is an amazing author, his conversational tone makes the books fly by, it really is as though you're sitting there having a conversation with him.
