Okay, good. Unless you are a fast reader, I would suggest you go directly to the chapter on Last Resort Technique and read it now. Then you can go back and read from the beginning.
Your M is in very serious trouble. I don't know at what point you think it would be time to apply "when all else fails" or what you had in mind to try (if anything other than what has been discussed), but don't wait too long thinking about it. Get down to really applying the things on the list.
You may or may not see results right away, but stick to it.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
