Your past will become a weight that holds you back and keeps you from living in the here and now. To put things in order means to put your past in order, too.
I recommend you dispose of anything that does not fall into one of three categories: currently in use, needed for a limited period of time, or must be kept indefinitely.
To truly cherish the things that are important to you, you must first discard those that have outlived their purpose. To throw away what you no longer need is neither wasteful nor shameful.
