I always work out of uncertainty but when a painting's finished it becomes a fixed idea, apparently a final statement. In time though, uncertainty returns... your thought process goes on. ↗
I've been painting and drawing and taking pictures as long as I've been writing music - and I've actually been drawing longer than I've been writing music. ↗
I don't have much of a problem with interruptions. I keep a detailed record of paint and materials as a work on each painting. I can restart exactly where I left off. ↗
