Responsible spending. I started out doing that when I realized there was SO MUCH out there and I had to make choices. So I've said no to a Cricut, Copics, stickers, chipboard and other packaged embellishments, Prima flowers, colored glitter (except for red and green), colored embossing powders and DCWV/other thick paper pads. I can avoid entire aisles in the stores!
Going totally cold turkey would make me grumpy, so I won't go quite that far.
