There is absolutely nothing wrong with reflecting on the past and over winding the mind or fast forting it. The problem becomes when we are doing that incessantly, constantly, unknowingly. And now we're going from a productive reflection to rumination. If we watch the content, if we allow the flashlight to return to the past with hem, we gat to still keep watch of it. Where is it? Is this still a good space to be into? Is this productive for me? And if not, get back to the task at hand.
