Someone once said that schizophrenia is more of a perceptual disorder than a mental illness; schizophrenics see and hear things that are not there. In our own way, I think all of us are limited by our perceptions, not to the extent that a schizophrenic might be, but simply by the fact that we all see things differently. When I paint, I like to give free reign to that difference, and avoid conforming to any particular style or expectation of what a painting is supposed to look like.
At some point, when I am well into a painting, my perception of what looks good on the paper or canvas begins to take over, and I start paying more attention to that than I do to whatever is actually out there in reality. The painting becomes a part of who I am, and how I see the world, and the satisfaction doesn’t come from whether or not it’s good enough, but whether I succeeded in capturing a part of myself in the process.
