it took me under two hours to read this ~200 page book and I probably spent too much time on it. it's really only about 100 short pages because each new rule starts on an odd page and most of the rules fill less than a page.
about half the book is covers the ruthless rules. the other half covers a bunch of "common sense" marketing truisms and advice. things like "to be interesting, be interested" and "challenge your professions rules in books and articles". to be honest, i found the common sense section a little more interesting than the rules section but really both sections were far too superficial. also, much of the information is dated. especially the section that describes the strenths of each advertising media.
