The 3 keys to happiness are making regular trips to the Goodwill to give crap away, the garbage dump to, well, dump stuff, and the shredder to shred all that important looking mail you saved but you haven't look at since.
To shred I went to Red Dog Shredz in Orangevale.
Their shredder is located inside a giant truck they have parked right in front of their location.
I took a garbage full of paper. It took them about 2 seconds to shred it. It cost me $9.
I also took a bunch of clutter to the Goodwill. I go to the 1 on Lichen Drive in Citrus Heights cuz it's literally right across the 80 from where I live.
I actually made 2 trips cuz I got the decluttering bug in me.
