I'm in art school and I have a big problem with precision and lack of "sloppiness" in my work. I'm sort of hesitant to try to improve in this area, however, because I suspect it reflects some sort of biological limit - maybe the size of some area in the cerebellum or something, I don't know. Am I right in thinking this?
You could try doing something that gives immediate feedback for sloppiness, like simple math problems for example. You might gain some generalizable insight like that speed affects sloppiness. Since you already practice meditation, it should be easier to become aware of the specific failure modes that contribute to sloppiness, which doesn't seem to be a well defined thing in itself.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
