The best way to tackle something that seems so big is to break it down into smaller chunks. So say you start in the basement work for about 20 minutes and then stop , walk away and do something else for a bit. Go back after your "break" do another 20 minutes or so and walk away again. Also have bins with you so you can decide right away what is going where. When a bin is full take it to the room that it belongs in.
GOOD LUCK and maybe for some extra motivation tape a pic of the treadle in a couple key spots so you can see it and know what your final reward is :thumbup:
