I use this as a daily reminder to 'unfuck tomorrow morning' each evening. The main thing I tidy up is my kitchen. I make sure it is clean enough that I can make my coffee the next morning without moving stuff out of the way.
I vacuum my floor as being on island is always very windy, therefore, dusty. I hang all my clothes and store that is the wardrobe. Tidy up the bed. Throw out rubbish. Sort out laundry. Rearrange all the gadgets, cable, etc.
