Like...... who even knows, man.
When I was in college I had one idea called Made Forest that I worked on really seriously -- that was the one I used in my pitch to comics companies, the one I felt was my strongest story. Later I got the idea for Runewriters, which I started doodling to "get it out of my system" and get back to my REAL story.
But the first comic I Finally Actually Started was a journal comic???
I eventually did start Runewriters, but Made Forest has become a story I'm not sure I'll ever actually tell.
Point is, I have Literally No Idea which of my ideas are going to stick and which are going to just float in limbo as a fun thing for me to draw sometimes. I have like three more mostly-formed ideas right now that could all become comics once Runewriters is done, but none of them are comics YET, so that could change at any moment. I could also have any one of a million half-formed ideas in my brain suddenly coalesce into a story idea without warning, and maybe that'll displace all the ideas I think I'm gonna create.
My feelings on it are, as long as I'm creating what I'm meant to create, it doesn't really matter if I finish 20 comics or spend my entire life telling one story! Lord willing, I hope to tell a lot more stories. But who knows!
