It is not for everyone and/or it does not necessarily work for everyone. It is not an exact science and does not offer a magic cure that can 'fix' everyone.

It depends on the therapist (e.g. personality, training, skill), on the client (e.g. personality, presenting issues), on the type of therapy or technique(s) used, on how we 'click' with our therapist etc. etc. There are just too many variables involved..
