Hi Anthony,
I feel your pain. I myself have bad days like those. "Patience and persistence" is a great motto and I would keep it and follow through.
One of the things that keeps me going is seeing great talent, great works and knowledge in this forum. It inspires me every day.
I have learned from a teacher once that it takes a thousand drawings to make a good one. It goes the same with painting. Hope you will find the stroke you are looking for.
