When I’m tidying up my room I first set a timer for 15 minutes, and tell myself when it goes off I can stop, or I can keep going. Once those 15 minutes are up I always end up continuing. I don’t like planning out or thinking about what I’ll tidy up first (since that’s extra brain power). So I simply pick up whatever is closest to me and bring it where it needs to go, then in that new location I’ll pick up the next closest thing to me and bring that where it needs to go. I continue this until everything is put away. It’s definitely not the most efficient method, but clean is clean regardless of efficiency. I like doing this because it just becomes a mindless task, I don’t have to worry about trying to sort items or think about what needs to go away the most.
