Not merely inspiring. I was inspired, say, by Three Cups Of Tea, but I'm not going to go build a school in Afghanistan tomorrow.

Not merely inspiring, but damn motivating. I've logged about fifteen miles since putting this book down.

Putting this book down, incidentally, is something I was unable to do after picking it up. I tore through it in about two and a half days.

McDougall's constant struggle for the "AND YOU'LL NEVER GUESS WHAT HAPPENS NEXT" hook is constant throughout the book and is annoying, but it doesn't detract from the story or lessen its impact.
