Uh... I have a folder called comics on my computer. There's about 3 I'm working on and off story-wise,(ghost story, furry noir, superhero satire), one actually being worked/published(religious chicken), one to-be published(teen zomb drama), a potential one-shot(zoo or safari animals), and conceptually, dnd but with bugs.
I only focus on 2 rn(chicks and zombs), but given they are both long form (beginning, indeterminate middle, end) i may switch between them and attempt shorter stories to keep my sanity. But of course, all these ideas are meant to be made over many years. And what sucks is I have abandoned so many stories written over my late teens and twenties, that i too wonder if im just having breakdowns or escaping daily life.
Well, that was depressing, sorry. If u are writing 3 stories, i suggest publishing one. Pick one u have the least love for, and put it out there, and prepare for critiques/advice. Use it to tailor your 2nd and 3rd story until u are comfortable publishing them.
Or just juggle them. It's difficult but not impossible. Take hiatuses if u can to work on another. But i do recommend AFK breaks, spend time with fam, pets, outdoors(weathers cooling down where im at. Im in the midst of a drawing challenge, but i might take a break for the day tomorrow. Its a miracle i havent burnt out yet...
Also, to everyone else, godspeed and good luck!
