Just spent a good chunk of the morning with a professional artist, and I have to say, I want to (kindly, gently, figuratively) punch “well known local art-education school” right in the nose.
That’s because the artist is in constant pain trying to work, and the reason this person is in constant pain is because the training institution didn’t check the students for proper form and body usage. Being an artist while rotating your wrist by generating your power to do so right at the wrist joint, rather than by turning from the elbow (to rotate the bones in your forearm and let your little joints and muscles rest/relax) is a really bad idea.
Ask a typist: “good form or you break.”
Ask a laborer: “good form or you break.”
Ask a musician: “good form or you break.”
Ask a (pro) cook: “good form or you break.”
Ask a weightlifter: “good form or you break (fast).”
It’s the same thing for art. It’s the same thing for everything. The better you use yourself, no matter how “obviously physical” the task, the less likely you are to find yourself in pain and struggling to do what it is that you love to do.
If you love doing something, it’s worth doing it well (and not being in pain). If pain is stopping you from doing what you love, let alone endangering your career, reach out. To me, or to somebody else, so we can help you get back to “doing the thing” with less strain and more joy.
