1. It was more than something I could handle for a moment. The reason why I started writing in the first place is because of Light Novels, and that lead me to writing my own story. But, it was not something I could write for my first story, I lack the ability and the motivation, considering how the story requires creativity.
2. Although I planned the basic premise and how the story will go, I learned upon writing it that it will be too much of a work. For context, currently there are 2 chapters, and the total words of those two chapters are 22k in total. And the problem I realized is that the story is incredibly slow paced that I don't think it will hook that much of readers. And those 2 chapters is supposed to be the only 5% of the planned story, and I can't really imagine writing more than that, because at that moment I lack the motivation and the ability to be creative enough.
3. Not sure about it being a big hit, but I think it is probably interesting enough. Lack of motivation and effort lead me from abandoning it, but I still plan on trying to get back on writing it. Currently I'm writing a work that I believe I poured my brain and effort, and if there's a chance, I will slowly write and complete my first story piece by piece.
Still, I wish motivation were something I could have infinitely, lol.
