What’s wrong with reviewing the past?

I see a lot of different jargon in the world of coaching and therapy. I came across a kind of therapy called Solutions Focused Brief Therapy. Wikipedia says - “ It focuses on what clients want to achieve through therapy rather than on the problem(s) that made them seek help. The approach does not focus on the past, but instead, focuses on the present and future. The therapist/counselor uses respectful curiosity to invite the client to envision their preferred future and then therapist and client start attending to any moves towards it whether these are small increments or large changes. To support this, questions are asked about the client’s story, strengths and resources, and about exceptions to the problem.”
This sound exactly like what I do in coaching to me – this would be appreciative coaching. Focusing on the dream and drawing on strengths to achieve the dream. I find the statement that “It does not focus on the past” a little painful. Which form of therapy chooses to focus on the past? Therapy, any therapy, is about the future. The past may be visited if it interferes with the present and the future. If it does, then it is imperative that we go into the past and resolve the issue. Without it, no amount of focusing on the future will bring change. Having said that SFBT has some interesting tools that can be powerfully used in coaching.
