Oh man, my friend Dana went through this exact thing last year. She kept this one client around for almost two years because the guy was "loyal" (her word, not mine) even though he called her every single day with some new emergency. She finally added up the hours in a spreadsheet and it came out to like 30% of her week for 8% of her money, and she felt sick when she saw the numbers. After she cut him loose she told me it was like someone turned the volume down in her whole life. Her only regret was waiting so long to actually look at the math. So yeah, having a real cutoff number helps, but the hard part is being honest enough to run the numbers in the first place.

Ever try giving them a theme so it feels less like hoarding? I did the same thing with motel signs on road trips and once I sorted them by type (arrow, neon, cartoon animal) it turned into an actual collection instead of a junk drawer. My wife eased up once I could show her the categories. Now we stop at bad ones on purpose and she picks the worst one of the trip.
