I needed my office to be cleaned up first so that I could be organized, as far as my stuff and my mind! Making it mostly paperless has helped immensely to save space and be more efficient. I (slowly) got everything out of the office closet and separated it into piles. The basement was next. Wherever you can store things is a good place to start. My rule was if we weren’t going to be using it in the next 3 months, it goes, unless it is seasonal of course. I had to let go of some sentimental items too. Hope this helps!
