Despite the fact that you already have good writing books to use, you keep looking for the best resource. The only reason I see for wanting Pauline Cullen's book is - you are probably substituting collecting for learning. Like, collecting more and more books instead of actually reading them and putting what you have learnt to use. That is a dead-end. The reason I can spot it is ...

But if we are to fight and overcome it, the only feasible way is, not to collect lists.
Collecting ≠ Learning
