I came across a great quote by Henry Miller that alludes to uncertainty, though Miller uses different terms. I knew I had to share it here. The life preserver analogy is especially powerful to me; again, no risk, no art.
“I had to learn to think, feel, and see in a totally new fashion, in an uneducated way, in my own way, which is the hardest thing in the world. I had to throw myself into the current, knowing that I would probably sink. The great majority of artists are throwing themselves in with life-preservers around their necks, and more often than not it is the life-preserver which sinks them. Nobody can drown in the ocean of reality who voluntarily gives himself up to the experience. Whatever there be of progress in life comes not through adaptation but through daring, through obeying the blind urge.”
