If you wander around hunter-jumper circles, then you know all about George Morris, or you can read his bio here. I've never had the nerve to take a clinic with him, but he is merciless, and calls it like he sees it (fat, sloppy, can't ride, ugly horse, etc.), almost the Donald Trump of riding. But he's been extremely successful and his latest book is all the rage. I have not read it, but plan to add it to my growing list of books to read. You can see it here.
