Thought Downloads & Models vs Throwing Away the Manual

I am working on my relationship with my sister. I for sure have a manual (a long, very detailed one:)) for her and for sure want to do the Relationships course in the Study Vault. But I’m working through the How to Feel Better one first, and just trying to make progress on my relationship with my sister in the meantime. Is it counterproductive to be doing thought-downloads and models on everything there if what I believe I really need to do is address the manual I have for her?
