|In the Groove.|
For me, it's the rhythm, the beat, the uninterrupted flow while working on the painting. Some call this "in the groove." Any action that takes me out of this groove - looking and walking around the studio to find something, talking on the phone, or studio visitors is a disruption.
I have noticed that I get more creative and do more painting if I stay focused in front of the canvas... That said, BEFORE I paint, I lay out everything. Everything. If my materials are out on the table and organized, there will be no need to stop what I'm doing (painting) and breaking the rhythm of the creative process. I learned this technique early as a young magician, laying everything out on the table and as a drummer - keeping the beat.
