If you are trying to declutter and you are struggling, why not grabs some boxes and practice the Box and Banish Method? Essentially what you do is take all those things you consider “maybes”* and put them in a box and…
… close it up. Yep, close it, and put it somewhere out of the way, like the back of a closet. Then set a reminder on your phone or in your calendar for a date about six weeks from now.
And after six weeks (or six months, but not six years), take those boxes and either trash them or give them away.
If you don’t trust yourself, recruit someone to do it for you. You’ll be glad you did.
(* Maybes are all those things you aren’t sure of that you may want to keep but aren’t sure. )
