We are going through a small refurbishment of our home at the moment, it was badly needed after our kids spent the first decade of their lives in our place. This all causes some disruption, but also has some upside: I need to pack up every single item in the house (and office), and make a conscious decision whether to put it back or not.
I tried doing a (minor) clean up 3 years ago, and can now see the exact items I decided to keep sitting at exactly the same spot where I left them. This was a great encouragement to do things properly this time.
Highly recommended, even if you do not need to repaint your home and office.
