I buy a shrub and plant it over the remains of my pets. Decluttering is hard work. There is very little that is essential so much is emotion in decisioning. i kept two paintings, my Doulton figurines and such like which are on display in my new home. I could declutter more and am doing that but more gradually now. Most storage units seem to be filled with stuff that has not the value of the storage costs when it is removed.
