I don't know if I would say "avoid flow" but "working on what does not come easy" is definitely a thing I found important in my journey from "kid who likes to draw" to "ex-animator". Whenever someone asks for advice on breaking art block one of my suggestions is to go draw something they hate to draw. This attitude became ingrained enough that when I was taking pole dance class later in life, my instructor noticed that, unlike most beginners faced with a new move they were having difficulty with, I'd make myself spend time experimenting with it instead of falling back to refining earlier basics I was more than good enough for at that stage of my practice. It's a good one to have, IMHO. And I sure as hell have found ways to complicate my work as time goes on. Constantly doing stuff I can knock out in my sleep gets boring; challenge is fun.
