social anxiety fears ME. singing a little song with friends (and strangers) and watching other people get up and do it too is soooo fun. I may not know a lot of popular karaoke-able songs but I definitely want to do it again :)
seriously, imagine the worst quality thing you can create in your medium of choice. Lean into the shit. Make it awful. Trust and believe you will learn more about yourself and maybe even stumble upon something beautiful.
