The inability to repeat
I'm finding it difficult to transfer what is working in some paintings across to others.
This is somewhat a double edged sword, on the one hand it avoids all the work becoming derivative of each other. This will help give a separate identity for each.
The downside of course is that nothing is working today. It's human nature to try and repeat what has worked before.
Perhaps I'm expecting to improve with every new work? This is not going to happen, maybe I need to accept that for every good piece there will be several bad ones?
