If you've read my posts before, you know I'm partial to the ~spark joy~ method outlined in The Life-Changing Magic of Tidying Up ($9.69 on Amazon) because it worked for me, and also like the more approachable 20/10 (twenty minutes of work, ten minutes of break) system from Unf*ck Your Habitat ($13.25 on Amazon).
But you can also simply make multiple piles and decide on your own terms what works for you, like Pretty Handy Girl. Or enlist the help of your most critical, honest (but kind!) friend. Or just decide you're keeping everything and organizing it!
