Slowing down and being methodical with my work is sometimes very hard. This painting would have progressed faster if I had taken my time and been careful with the placement of the basic shapes. Unfortunately I was forced to almost start over after an hour into the painting.
Deliberate practice is paramount. I could paint or draw the rest of my life without any considerable increase in skill, if I do not practice deliberately. I must analyze my work, see the issues, then correct them. If needed I must redo the same work multiple times to correct the issues. It is so easy to work constantly ignorant of bad habits repeated over and over. The only cure is to seek out the unwanted habits and systematically eradicate them.
