I don't have any problems with the plot, settings and etc. The only problem I have is the details, info dump necessary to the novel and character interactions.
The details is a bit easy but as the novel goes on, more details needed to be added and it almost confuse me which is which. In the end, I completely get stuck in a cycle of not being able to think of ideas and basically get stuck half-way. Basically stopping writing due to it.
The info dump, while a bit necessary, isn't actually forced into my novel. I only added a bit info to some structure on how things work and making things logical in my novel(I don't like to write plotholes so I tend to work a bit longer to make magic simple yet not easily attainable and be overpowered in my novel).
Finally, Character Interactions/Dialogue. This is the hardest of the problems regarding my novel as while I do know how my character would act, I can't make it fluent and be realistic that I tend to stop writing entirely because of it. Basically, I don't know how will my character speak, how its tone would be and the insufficient knowledge of details to add, this this the main reason why I can't continue writing my novel.
I know I kinda BS myself because I'm just too lazy to write but this is mainly the reason why I slowly procrastinate. I actually love writing and not only that, I worked hard developing my novels to be good. However, because I couldn't really write the novel the way I wanted it to go(had to scrapped some ideas to fit and goes well into my novel, making it sadder the more I scrapped more ideas the longer the novel goes on), I kinda hurts me to continue writing.
