It's taken me about 5 year to figure out a laundry system that works me!  I tried doing all I could on days I felt good.  I tried letting it pile up.  I tried designating a day & forcing myself to do no matter what I felt like.  Alas, what works for me is a load a day.  One load a day, whether I have 1 load or 5 loads.  One load a day will keep the mess at bay.
