Cognitive Behavioral Therapy 101 Let's say that I'm completely green about psychology and CBT (like I really know nothing, apart from that CBT exists). Is there a good introduction/ seminal work, but with relatively low barrier of entry and not too massive (something that could be learned/ studied in several evenings)?
I'm aware of this question, but what I'm looking for specifically is a book or a more involved/ in-depth resource.
I think that you should look at one of the more well rated books on CBT. 

Aaron beck is the father of CBT so maybe start with his book if you can't make a decision.
