Classroom - I moved into the room of a teacher who retired and didn't bother to take anything with her, personal or professional. There was so much stuff in there, one could barely walk. Extra bookcases, materials that hadn't been used in 5 years or more, old tests and paperwork, enough teacher supplies to distribute among the entire building. Some people have no pride! I worked my rear-end off and got it decluttered, simplified, personalized, and ready for day 1 of school, August 25.
My closet floor.
