I am planning on going into psychology and hope to someday open my own practice as a clinical psychologist. I believe that I have a very good understanding of peoples personalities and their behaviors but I fail in the area of critical thinking. I lack the ability to disect peoples problems and find the root of the cause, and even if I did find it I probably wouldn't know what to do with the knowledge.

So far most of the books I read are just self-help books and are focused on helping the reader. I need something that aids me in helping others rather than just myself and teaches me the process of going about it. What books would you recommend to a beginning psych student who is interested in doing talk therapy? What are some other must read books for the field of psychology?

Thanks.
