I still like to read psychology and therapy books, but i've had to cut back just for the reason you are talking about. I read things that other therapists have said and then get upset, thinking that my t must feel that way also. I found that reading too much about therapy just added things to my worry list. Also, it kept my therapy in my head, as an intellectual process -- the more i tried to understand it mentally, the easier it was for me to skip the emotional work in my sessions. It was a form of control for me. Reading about it made me feel like i was in control of what was going to happen in my sessions -- i'd be all prepared for it -- but that prevented me from being able to relax and let the process unfold naturally.
