We know from studies, especially things like grief and studies on trama processing, that things like rumination and dwelling on the past are necessary components to emotionally cess. And then if we emotionally process, this essentially causes us to move on. We also recently talked a little bit about counter factual thinking, which, just to give you guys a refresher, is when we think about things that did not happen. It helps us correct our behavior, and it also sort ofa creates a sense of regret that can be used as a motivational drive.
