I don't believe therapy is for everyone, and I don't believe being a therapist is for everyone. A proper match is also critical.

By my reasoning, a life changing positive outcome in therapy is highly unlikely. Statistically, let's say 75% of clients are suited for therapy while 25% are not. Let's also assume 75% of therapists are competent while 25% are incompetent. This equates to a little more than 50% of clients who have the potential get any benefit at all from therapy. The remaining % of clients are doomed from the start because of either their own limitations or an incompetent or dangerous therapist. Of the 50+% of clients who are suited for therapy and are with a competent therapist, a significant number may have personality conflicts with their therapist or are with someone practicing the wrong modality for their need. I'll be generous and say half of all client/therapists matches are adequate. This equates to a little more than 25% of clients who will have positive therapy outcomes. Of that, I'm estimating only 10% will have life changing positive outcomes while the other 15% have only mildly positive outcomes. IMO clients in the in between range are better off saving their money and doing something else with their time. The doomed % will lose more than time and money.

Therapy is a gamble, and therefore very flawed. Odds improve when people are willing to change therapists mid way. I hope I'm in the favorable 10%.
