I assumed this was going to be about avoiding flow while doing actual work, but this is only in the context of practice and training.

I can see the argument for avoiding flow and focusing on your weaknesses when your goal is self-improvement (and to take the jump from there that it's important to set aside some time to focus on self-improvement), but that doesn't apply when your goal is actual output, which is the majority of the time when it comes to most of our jobs

This is a good point where professional musicians and other performers are in a bit of an unusual position, their ratio of practice to "productive" is pretty unusual in other fields. I suppose (professional) athletes would be another example.
