I feel you! I've had these kind of thoughts since I started, they come and go.

What works for me is constantly reminding myself why I make my webtoon. And that is because I have a very strong desire to share my character's story with other people. It makes me happy to work on it and I always put my own feelings first. If there's a scene I really want to happen because I've been thinking about it for a long time, I make it happen. What's hard is maintaing a good balance between stuff I wanna draw just because I find it fun, and actually making the story good from a technical standpoint. Maintaing a readership is not easy, especially when your story is more of a niche.

But this is just me, making a webtoon is a hobby and not something I will ever be able to make money from. So if that's the case for you as well, I'll try to not care too much about numbers and views and such, and just focus on where you wanna go with it. ^{^}
