Sounding like a broken record.

          But working through it! You've got to!  I can't tell how long it will take to get the groove back but it's important to NOT make the efforts seem insurmountable.  For now I've been doing smaller gouache works.  I picked up some more clay.  I use Low Fire White Earthenware.  So I have been working 3D with great satisfaction.  I have been taking a little time to go back to reading about other artists, contemporary and historical, to glean any inspiration I can whether working processes or whatever!
         You can always find some great clips on Facebook.  I read a short article on Alex Katz.  Watched a You Tube on Ingres.  Read another one on Frank Auerbach. I was wondering, "have I looked at too much art that has caused this block that I have to work through daily waiting." Nothing to do but put one foot in front of the other and go do another load of laundry!  Some samples below.
