The biggest obstacle to getting organized (and staying organized) is deciding what to keep and not to keep. If you are experiencing difficulty finding that “joy spark” to help you make your "keeping choices", tweak that perspective and…
make your decisions based on whether you USE AND LOVE each item (yes, you should both USE and LOVE a "keep" item).
If you still need more guidance, consider applying some H.O.P.E. Power:
H-Is the item Helpful?
O-Are you Obsessed with the item?
P-Do you have a Personal connection to the item?
E-Does the item help you with Everyday Efficiency?
