Perhaps my perspective is different because I am not in therapy to learn about myself in some general way - I think I know myself - I am there for a specific thing which may or may not be fixable through therapy.

I see nothing wrong with trying a new therapist. Talk to the old therapist if you wish, tell him you want to try a new perspective or whatever, and, if you feel it necessary or beneficial - tell the old therapist the reasons, and talk to the old therapist about making a plan to have another appointment with that old therapist a month or so after seeing new therapist to discuss which one to continue with. I have never had a therapist object to the idea of checking out other ones. I would run miles away from one who did.
