So I took everything out of the dining room (besides the furniture, that is), and then slowly brought it back in. By doing that I was able to see what items I didn't want in there. What items I didn't love. What items were just stuff, instead of needed/wanted things.
It contains my little corner shelf. My dining table. And my buffet which holds the kid's school items. That's it.
One bag of stuff ready to be donated. One room down. A million left to go!
On a side note, we also cleaned out part of the garage and got rid of a pile of stuff on the curb. I'm glad someone else is able to make use of the items and glad we have some cleared space.
