Make a date to remove the items you’re decluttering, rather than letting the boxes of garbage or “to the thrift store” stuff accumulate indefinitely.
You can schedule a trash service or in some cases, a thrift organization, to come pick up your stuff. Then you have a target date to work towards – after all, you don’t want to waste their time by only having a few things for them to take. Make the most of the pickup and get rid of as much as you can all at once!
If you’re really going gung-ho, and the stuff you’re getting rid of is genuine garbage, rent a dumpster for a day and fill that baby up to the brim.
