Step 1: identify that something no longer brings me joy
Step 2: think that I can get money from selling it
Step 3: post it online, bring it to a reseller, put it on my lawn with a price
Step 4: frustrated, realize that it isn’t worth anything
Step 5: bring it Goodwill
Step 6: relief and freedom that I have less
Repeat.
Creative Chaos 
Having done this more times then I like to recall I learned one man’s junk is another man’s junk
Haha.
