It depends on the therapist and the patient. Therapists, like every other profession has practitioners that are really really good, some that are mediocre, and everything in between. Patients, too, come in all shapes and all sizes.

When therapy works, it works really really well, and relatively quickly too. From casual observation of friends and other people around me (ie, as a regular person; I'm not a health care professional.) I've seen people manage to make sustained healthy changes in just a handful of sessions. I've also seen people not improve, or take far longer.

If you've been going to therapy for more than a few months and haven't been improving, it's time to change something up. Therapy should be "something like that".
