Evaluating what to get rid of,,,
1- Does this thing work?
2- Would I replace it if it were broken or lost?
3- Does it seem potentially useful—but never actually gets used?
4- Was I “saving” it?
5- Does it serve its purpose well?
6- Has it been replaced by a better model?
7- Is it nicely put away in an out-of-the-way place?
8- Does this memento actually prompt any memories?
9- Have I ever used this thing?
