Realize that change and downtime are important. I found that if a painter relates to objects only through vision, his work is much less original than a painter who walks up to the object, smells it, throws it in the air, and manipulates it. The variety of sensory inputs allows you to create a visual image that has all kinds of dimensions bubbling up inside it. We are still a multimedia organism.

Flow depends on the ability to engage in intense concentration.
