downvoting is dimensionally-collapsed feedback and requires nuanced examination to internalize well. so it makes sense to self-examine a bit, then dampen the internalization to account for ambiguity (rather than quitting). that builds both flexibility and resiliency.
sometimes you get no feedback at all, which is even more ambiguous. feedback always exhibits degrees of ambiguity, so we gotta figure these things out at some point in life (well, we don't, but that's worse), and this is a great place to practice.
