I'm always working on my chapter one. With my current work, Nina, I'm just trying to get myself towards the end of the project. There are other stories I would like to work on, and some I do not think I can illustrate but would like to someday work with an artist. Time is limiting when you have a lot to say, which causes me to sometimes just combine ideas into other stories.
Even though I have a lot of ideas, I can not bring them into fruition if I can't even finish the Nina story. You could say it's a challenge and self-discipline, because it is so easy to quit, a lot of people do abandon their projects. I can easily start writing the first chapters for 10 different stories, but none of them would be satisfying for me if they are not completed stories. Though, I have made completed stories before, none of which are comics.
So, I hope you also don't stop working on your comic! You never know what you might learn along the way!
