Declutter / spring clean question?

Pace yourself, if it takes a couple of days so what. It will drive you crazy if you try to do it all at once. And I find that listening to upbeat music helps too, takes ur mind off of it all being so overwhelming. As for technique, it's really just like you said...if you don't/won't need it throw it away, if you don't/won't use it throw it away, and of course keep everything you love. Good luck!
