Projection?

Hi everyone.

I know the very basic concept of projection and lately I’ve noticed just how much I actually do this in my own life and have decided to try and take some control of this.

I just wanted to ask if there are any particular books/articles/videos that are mandatory reading/listening on this concept? Ideally I’d like to go very deep into this and really understand where it comes from and why it happens, and to become a better person.

Thank you :)
