There’re many reasons why our childhood and past are often looked into when we go into therapy. What Penny explains is the explanation that makes the most sense to me.

Our past forms our present, and largely dictates how we approach the future. If there was trauma or some issues that we can’t come to terms with from our past, it will reflect itself some way in the way we lead our lives.

Understanding and coming to terms with the past usually helps to ensure lasting change.
