Awesome post annhoyblog, it takes courage to make that decision to let go of the things the mind tends to place so much value on. I've found I can also use that experience of wanting to buy more stuff or thinking about the stuff I have and/or will have to understand who I am on deeper levels of my mind better. Usually when I get "possessive" like that, it's cause I'm using those feelings to suppress fears or stresses within myself, so I use the possessiveness as an opportunity to bring those suppressed parts to the surface.
