play more hacks and make more levels. that's my best advice, i think this mostly comes down to a matter of experience. contests in particular are good to participate in for this reason on top of giving you a clear extrinsic motivator for trying new stuff out more if you need it. maybe it'll bomb, maybe it'll do well. either way you'll learn something from it.
i graduated college without having to to any extra semesters. only just barely but it still counts. i also watched some anime i liked.
that's about it really, admittedly i feel like i've become a bit numb to this whole "being alive" thing at this point.
