Saying "I'm a content creator" as a catch-all because you make videos, you produce podcasts, you draw, you write - you do too many things to feel like one word encapsulates it all?
Tell people you're a multidisciplinary creator, but do not lessen yourself or the work you do by calling it "content"

creator is still a hefty, utilitarian word that works, don't get me wrong
but strike the idea of "content" from your lexicon - it cheapens the thing, it commodities and codifies it in the worst way
it doesn't mean anything
there's no description in it, no tooth or tangible definition
