I know someone who trained to become a teacher and attached to this were required options at the college, one of these was art. She found it most unpleasant with nasty critiques, and personal attacks in presentations. The final straw was the whole room being forced to act out their own suicides in manners chosen by the 'artist'. Basically, she decided I'm not doing this anymore whist still doing the rest of her training.
A few months later her art tutor spotted her walking across one of the quads, "Hello haven't seen you in a while. I'll need to see your work." Her reply with restrained panic, "you can't it's a secret!" expecting to be called out for this BS, but he accepted it with great interest.
Good God she thought, what am I going to do? I've got nothing! Nothing! Wait; my work will be nothing. At the end of the year, she submitted a sheet of A4 explaining the work with a folio of blank sheets of art paper, and a dozen cassettes with nothing but empty hiss on them. She got an A.
