Psychotherapy is for anyone and everyone.  For some, psychotherapy is a luxury. Many continue in psychotherapy for years because they continue to find value in meeting regularly with a mental health expert.  Others come to treatment to work on a specific problem that is confined to a specific yet important area of their lives. Still others find that an underdeveloped sense of themselves and others has resulted in longstanding patterns of tumultuous and or unfulfilling relationships–perhaps extending into difficulties excelling at or maintaining a job.

Yet another amusing paradox of psychotherapy is that people often enter into treatment with the intent of addressing a specific issue, but engage with a course of therapy because it has so much value outside of that particular difficulty.

In my experience, people who overcome their apprehensions about psychotherapy and come in for one or more sessions are surprised at how much it can offer.  One irony I have discovered about those who eventually experience the benefits of psychotherapy is that internal conflict around needs and needing can even be the main reason why it takes so long for them to seek treatment.
While everyone can obtain benefits from psychotherapy, I must add a few caveats.  Psychotherapy is not an antidote to either societal problems or unfavorable life circumstances.  That is, psychotherapy does not substitute for activism, nor does it alleviate poverty. However, many do in fact discover that they are more effective at engaging with social problems, or find “luck” finding a job after beginning psychotherapy.  However, the distinction between working on your relationship to existential conditions like world hunger and personal tragedy are different than the states themselves–the former can be worked on in therapy while the latter is not best dealt with in the psychotherapist’s consulting room.
Yet another amusing paradox of psychotherapy is that people often enter into treatment with the intent of addressing a specific issue, but engage with a course of therapy because it has so much value outside of that particular difficulty.  When the presenting problem eventually gets resolved in treatment, clients continue to attend and profit from therapy while seldom attributing their success in resolving their presenting complaint to the course of therapy. While you might think this would discourage therapists, I believe this phenomenon is a great compliment to the art of psychotherapy; the benefits of a good-enough treatment are so broad and diffuse that patients feel its value to such an extent that the original problem becomes an afterthought.
