I personally don't know CBT very well to be able to tell you what the basics of CBT happen to be.

From my own experience in other frameworks I think that having declarative knowledge of what you want to do procedurally is helpful for being able to perform the procedural part. Understanding the basics of a topic well enough to break them down into atomic bits is hard but I don't think that topics like CBT are inherently structured in a way that they can't be reduced to atomic bits.

But if you lack the ability to know the basics of CBT well enough to state them at a atomic level you fortunately aren't out of luck. A straightforward way is to to write Anki cards that ask: "Is A or B the right way?" The learner has to only remember one bit of information to answer the question.

From the start of the book, you could form the card:
Question: Do your moods get created by your thought and attitudes or by external events?
Answer: thoughts and attitudes

I think it's worthwhile to study the basics of CBT. I downloaded the downloaded the ebook. Hopefully I will have a good answer about the basics of CBT at some point in the future.
