I've done some digital uncluttering - extra copies of pictures, files I haven't touched in more than five years. Uninstalled games I don't play (kept the installers in case I want to play again sometime).

Physical file-wise, threw out some saved writing-related articles because I never looked at them again or have found a better/clearer/more fun article on the same topic.

Put the few remaining vitamins into the new bottle.

Burned a couple of sticks of incense. That counts as uncluttering, right? Fewer sticks! XD
