Oh yeah, starting your comic is hardest part in actually making it.
You can plan all you want in the world, even have a decent skill in art, but unless you actually start, you'll never find yourself improving or discovering your limitations.
When I first started, my work was crap. Like real crap.
But through time and realization, I found ways to improve my comic, like inking with an actual brush, allowing my speech bubs to step outside the frame, and a color scheme that allows my monochromic comic become something eye-popping.

Also, having a dedicated project allows you to find out what you can and cannot draw, then you find out ways to work around that, or find ways to improve.
So in the end you gotta have some patience for yourself and your skill, but have something to work on to get better and test your limits. Now I make 4 different comics a week minimum, and even that's not enough for me. I just gotta keep working in order to make that buffer, work on guest comics, possibly start a website, begin on a new comic sharing site, and test out a Q&A livestream once I reach 150 subs total. (I'm currently around 90. It's not too far off) I would've never imagined that I would make it this far. Sure, I might be going mad, but I rather be mad and stirring my creative juices than sitting around like a couch potato as I once was.
If light that spark, you might get a little flame to see through the darkness, and it can go out at any moment. But if you take care of that light, and you might end up creating a real bonfire.
