Its also how that emotional past or past experiences build up onto our psyche holding us down making us incapable of seeing things with a broader perspective.
It is in part the story of all of us to a certain degree. Some carry less because of the tools they have acquired learning to let go. And some carry more, with no tools to treat the emotional past one eventually drown in there own persona built on shadow memories. To people like this the present is a place that is not lived but occasionally visited when for some reason they are able to escape for a short time there emotional past.
