Query: More Wisdom than One Man Can Glean

I can hardly believe all of this wisdom came from one man. It would take me a hundred years to learn all that is contained in this book from any other source. Before this book I thought my own writing skills served me well enough, now I see clearly how much I didn't know. I'm sure to refer to this book over and over, it is a must have for any writer's library.
