“You can’t make your best work when you’re concerned about success or failure.
“The very act of thinking about the outcome creates an anxiety that holds you back from a daring move, that makes you afraid to touch a good-bit, or more likely, unwilling to stop when it’s truly great.
“… We’re training our hand skills by running this marathon, but we’re also training our judgement. The more pieces you do in a row, the more shots-on-goal. The more likely you’ll learn to recognize when it’s time to push something – or – when you need to stop and let something stand as you’ve made it.Marc Taro Holmes, “Sketch vs. Painting“
If you never overwork a painting, you’re stopping yourself from discovering what else you might achieve. Dare to stop later and later.
If you never underwork a painting, you’re stopping yourself from discovering what you might convey with less. Dare to stop earlier and earlier.
