It is a misconception that a client comes into therapy for happiness. More accurately, they come into therapy for a movement in a direction where life becomes more sustainable, enjoyable, less painful. This is not the same as happiness. It could, for instance, make a client very happy to ritualistically cut their wrists. The definition of happiness is so broad that it is almost meaningless. What has more objective truth to it is that the client comes to therapy for a change.
