There's a good blog post on ways we talk ourselves out of decluttering certain items. I know I've used a few of those arguments on myself. I am getting better at realizing when I'm talking myself out of getting rid of something and when my reasoning is ridiculous.
A bag full of foam stamps, a little over 40 of them. Most of them are still new. At least I do see a lot of clearance stickers on them, but still... money wasted. I've been moving this bag of stamps around my craft room since I started really decluttering. I kept thinking about the money spent and that I might actually use them someday. Really? Get over it. I haven't used most of these, I probably won't ever use most of these. Out they go! I kept just what would fit into a small metal lunchbox and all the rest (all of those above) are going away. Less is definitely more. =)
