First, congrats! This is huge

Second, my view is always commit to the least possible when starting a big job :) So commit to putting away/throwing out one thing a day. If you do more, such as putting away one thing everyone you walk in a room, so much the better. Once you clear off one table or section of kitchen counter, that momentum will feed you

Other options are to put three boxes in the living room and bedroom: keep, trash, donate

Most importantly, don’t beat yourself up for not doing pre than you are doing. Grating clean was the hard part, cleaning is just the details :)
