all this crap

I stand surveying my storage unit. It's packed with a bunch of boxes. Today it will get another load with furniture. Wow - all that stuff is mine. All this is baggage. My personal history. It's kind of cool that it's there - my personalities boxed up in brown boxes. But at the same time, it's so much crap, how important are these things? Could I just leave them behind? By doing so, would I lose/forget some part of myself?
