Nothing Interferes With Creativity...

One of the little quotes I like to do. I have a tremendous problem with resentment at times and I have to remind myself that it affects my attitude in many subtle ways. This is one I was not aware of... Sometimes there is this tendency on my part to get down on myself. Reminding myself that things could be worse helps. And that sometimes it does a bit of good to stay grateful if at all possible. .
     My images always come out lopsided. How does one correct this?
