I had a breakthrough of sorts last weekend in my enactment of water color layering. I can only describe the process as an act of faith — that is, of trusting that the object of the painting will eventually look the way one wants it to (it really does not come into focus until near the end).
I also enjoyed noticing that the banana (the real one in front of me) had some orange glow in it, a revelation that occurred only after an enforced relaxation of my thought process and a simultaneous deep-looking.
