Thanks for everyone's suggestions!
I'm 6 days off work this week and day 1 consisted of taking inventory of all my clutter, I had a good friend help with this. I had 2 bags of old clothes I didn't need/want! The ones in good condition are being donated and the one that are not are being recycled (I didn't know this was a thing, thanks to my friend!).
I still had even more clothes that I never wore or wanted along with some really cool things as well, those will be sold online.
I'll post an updated after my first sale!
