Query: If you've read "Life Strategies" don't bother

If you've already read "Life Strategies", you'll find this very heavy on repitition, not just in terms of general themes (e.g you have to insist that others respect you) but even the case studies and examples McGraw uses. It seems as if he took the core of "Life Strategies", added on one good additional chapter, and proceeded to publish. If you haven't read McGraw's other book, you'll certainly enjoy and benefit from either of the two. He's straightforward and certainly in your face the whole time. In both books, he could be more expansive on how you get things done, even if you know what you want to do. Using the previous example, it is one thing to say "insist that others respect you", but how you get insensitive folks to actually do so is more difficult, so more elaboration on the actual how to's would help.
