Split Personality : Hoarder Artist in a Minimalist Life

As an artist I am a natural hoarder as I am inclined to keep all sorts of items for possibly future use and save things like sketchbooks. I make and collect art and books and these take up space. But I have found that life works more efficiently when I have less stuff and spend less time cleaning and more time working on what I care about. How do I find that balance? When do you let old art or art supplies go?
