Splurge or not?

I just found a book I'm considering getting, even though we have zero money. Something along these lines is badly needed! In the 7 areas of desperation, 3 are non-existant for me, one I'm drowning trying to accomplish, one is a nightmare, and the other two are just ok. What do you think, is that just cause to budget in a book?
