Revelation: I am a serious studio pack rat.
We are in the final stages of the shift. Tonight we moved a U-haul's worth of shelving, cabinets, tables, and paintings. I have decided to donate or destroy any work that has not sold and that I don't want to keep, and I'm sure I will not have to buy art supplies for many years!
Envisioning the future: shelves and cabinets emptying as the paintings find new homes and the supplies are used up. These empty shelves and cabinets will then also find new homes, the studio will become spacious and I will avoid cluttering.
This is the idealized version of the future from here where I sit at 3am, exhausted but feeling optimistic.
