I'm an artist, not a writer at all.
I have my own ideas and stories but I don't have the skills nor the interest to write, I chose to develop my artistic skills, mostly because that interested me the most and I could achieve a finished product faster.
I also have no need to tell my stories, so that's also a factor as to why I don't draw nor make my own comics, I'm fine drawing for others, but whenever I want to work on something small for myself, I seek out a writer (Sometimes I rely on my partner/friends or hire someone) to figure out things, especially the script.
