Does anyone have tips for how to train yourself to put stuff away after using it instead of accumulating an evenly distributed layer of debris on every flat surface?

In our family we call it 'flat surface disease'. We either decorate it or let things fall into piles. I forced myself to enjoy clear spaces. Set a timer. Clear everything off. Put everything back where it goes. Take a picture. It's easier to clean with less items in the way. Do it every day. Think of it as resetting it for the next time in a few seconds… instead of spending all that time clearing it off again.

One thing I have learned to try to do is to look behind me or look back when leaving an area. Then I can see that I may need to clean up. Another thing that helps me is to set a timer for a couple of minutes and pick up the area.
