My mom is a hoarder*, so decluttering is sort of an on-going thing for me, even when I technically don't "need" to declutter, because I have enough space for all of my stuff.
As it's springtime, I am doing my regular spring clothing cleanout. And...as I'm coming to terms with my butt never being a 2/4 again, but entrenching itself firming in 6/8 territory, I'm getting rid of A LOT of pants/tight-waistbanded skirts.
Aaaaaaaand forcing myself to finish painting my apartment, so that I can transfer the extra touch-up paint to mason jars, and get rid of a dozen gallon paint cans.
I also pulled down my MASSIVE box of mending (embarrassingly massive; I think I had something like 30-40 items of clothing in it). I got rid of everything that's so old that I don't like it/won't fit in it anymore, and have been making myself mend 1-2 things a week. If I keep it up, I'll be done by the end of the summer, and I can keep something else in that giant bin (maybe extra pillows & blankets).
*An actual, Hoarder TV-level hoarder. Little pathways through rooms stacked high with crap & all. Sigh.
