According to Frost and Steketee’s Stuff: Compulsive Hoarding and the Meaning of Things,
Hoarders need to convince themselves of 3 things in order to let go of stuff:
1) to know that the item won’t be wasted
2) to know that it goes to a good home
3) to know that the opportunity the item promised is over
Now which of those do we have any real control over?
No wonder we keep so much stuff!
It takes so much energy to make the decision to get rid
of something when we feel such responsibility toward it.
But with practice it can happen.
