It wasn't intended to be client-blaming, rather, IMO it is client-empowering. A therapist does not own your life or your emotions. They can't fix the problem, but they can help you see where the problem is and hopefully, what to do about it. I believe that all adult clients are able to do this, but it takes time, and commitment (to getting better, not commitment to seeing a particular therapist), which if the client does not have, they simply will not get better, no matter what the therapist does. It is the client's actions and behavioral changes that actually must solve the problem.
