I don't think I'm too smart for my therapist, but I do think that therapy is not designed with highly intelligent people in mind. Some therapists and clients can still make it work, I think, but in my experience it works best for people in distress or who have diminished capacity due to emotional overwhelm--which at times is where I land when I'm in bad shape. So when I'm a wreck and can't process or keep up, I get less frustrated than when I'm hitting on all cylinders. Even when my brain is crap, however, I would still not pay for CBT.
