There is no doubt about it ... this painting thing is hard, but try not to be too hard on yourself. I say this, not necessarily because I follow what I say myself but mostly since I have started teaching classes again ... I see students wrestling with the process vs. the finished product.
All too often, the finished painting becomes the goal and the process is forgotten ... the love of the paints and the brushes and the feel of the rough canvas ... even the smell of the oils. That is the love. I won't say that I am not guilty of this myself but when I slip into that place where I am judging what I am doing ... it is then, I try to remember that I love doing this ...
