When I stopped stressing that I wasn't selling work, then my work started to sell. Truly this proves that my thoughts create my reality. I am happy again, and it's all because of how I changed my perspective on the world and on myself.
There's no reason for me not to appreciate my artwork just because I haven't sold a painting. I am still getting it out there. I am showing it. It doesn't need to be my means to make money. I can still be good at it without making money at it. I don't need to be a professional painter to be a good painter.
