This book is a brilliant treatise on new business development. I found myself violently agreeing with just about everything written. I read more than a hundred sales books each year and it is extremely unusual for an author's views to match so well with my experience - which was selling high value products and services across many industries all over the world.
I only have one (minor) disagreement with chapter 8 "your Sales Story". I maintain a strict definition on what a story is (see my other recommendation "Putting Stories to Work" by Shawn Callahan). For me a business story is a narrative, with a time and place, unexpected events, a character and it makes a business point. Mike Weinberg's company sales 'stories' are really assertions - well structured assertions but not stories.
If you need to bring in new business, this is the book. Highly recommended.
