Most of the time when I paint, I want a good, clear, clean, accurate image of my subject, I want to apply the paint carefully so that it enhances the image and is put on correctly, and I want the narrative of my painting to be clear to the viewer. The 'feeling good' sketch I did has none of these things, yet it speaks to me, and only to me, of things I need to hear. So the near-as-possible-to-perfect painting (at this time) is not the only way to go to produce something that has value to me, and that has been an interesting lesson.
But now I'm back to my usual work, and loving it as much or more than I did last week. (Before the 'Revelation' :D) I'm still painting Dreams and Dogs and Horses, but now from time to time, and just for me, I'll be painting personal emotions. There is so much more to Art than you would think.
