My cousin Cathy is a beginning watercolorist. Recently she unknowingly gave me some fodder I can use while I'm teaching one of my future watercolor workshops. She decided to quit on the painting she had been working on and told me why. I've decided I can use her assessment of "quitting time" when one of my students asks the question as in the following example.
The befuddled student asked, "Mr. Toon, how do you know when a painting is finished?"
The wise teacher knowingly responded, "When you decide it's time to quit before you mess something up you can't fix."
