For the last several years, I've had many of my things stored in the house I formerly lived in (due to the graciousness of my former housemate!). One of the things I really wanted to do in Maryland was to go through it. I planned to give much of it away and catalog what I kept so I no longer wonder what I have and will be aware before buying duplicates.
I think having stuff I use is fine, but especially stuff just being stored can be a burden. I wanted to cut my belongings down as much as I could. It ended up being a big project, but I'm really happy with the results. I got rid of about 2/3 of my stored clothes, toiletries, and etc and organized the rest, taking videos and pictures of the layers in the box for future reference:
I hope I'm not a gypsy for much longer. Regardless, living lean and simply is incredibly freeing. I still have much more than I need but this a step in the right direction!
