Whether you have a formal collection or just a bunch of things, all that stuff can overwhelm you. Even if you don't have museum-quality items, setting some policies can help keep it all in check.

Unclutterer explains why you might be able to get rid of a few things if you take a curation approach:
Museums sometimes remove items if they are redundant with others in the collection or if they are "of lesser quality than other objects of the same type in the collection." They may also remove items that are "unduly difficult or impossible to care for or store properly." Items may also get damaged to a degree where they no longer fit within the scope of the collection, and those items would be removed.
This approach probably won't work with a pile of junk. This tip is more for that memorabilia from high school, university and other life events. Do you really need all those T-shirts? Will one high-quality T-shirt fit in the "museum of you?" Check out for other lessons to learn from museum operations.
