Sometimes I read a blog post that is so spot on that I wish I had thought of writing it. The important distinction between de-cluttering, essentially re-organizing your crap, and de-owning, getting rid of your crap, is one that is unfortunately often overlooked.
Joshua Becker’s post “Don’t Just Declutter, De-own” does a fantastic job of laying out the differences and most importantly the benefits of getting rid of your extraneous crap.
