In think what always trips me up when trying to make a zine is that I get caught up with attempting to be technically precise. But it's hard not to when I spent my childhood running around printing presses and I have the technical knowhow. I eagerly advocate for the "do it; and if it must be messy in order to get it done at all, do it messy" ideology but struggle to apply it to myself.
I miss my old zine club, where I got to make zines with people who barely knew any of those things and made them for the expressive joy of making something, where the adults just doodled and the kids made the funniest comic books you have ever read in your life. It made it easier to just be messy and slap it together.
