back with bonus thoughts about different motivations ppl have for writing
this is gonna be an oversimplification, but some ppl are artists, some are entertainers, and some are fanatics (in that they're compelled to get the words out by any means necessary)
the advice to "write for yourself" is getting bastardized and/or misinterpreted to mean "do not ever express disappointment if a piece you worked hard on does not find its audience," but what it actually means is "only dedicate time & effort to ideas that excite you"
