I'd like to participate.
A flooded basement the day after Xmas has already forced me into action. Just one room flooded so EVERYTHING from the strorage room got moved to the semi useful room. A good time to clean out both, I guess, since I still have a bunch of my 5 1/2 year olds baby toys. I posted 5 things on the local buy and sell Facebook and sold all 5 already! Made $30! Unfortunately, all the other good stuff to sell is behind other stuff that needs to be purged first.
Aside from the basement my other main goal for the year is to do something with my guest room. Right now it's where I toss junk. Not everything needs to go, but it needs to be better organized at least.
