Honestly dude thank you for the compliment and all but I don't think I'm really the best person for this but I'll give you the best advice I can think up
So for one I'd say determine your writing style, just make a book in your drafts and keep writing out a part of one chapter of your own and just keep writing it differently until you find one that just brings out more I guess
Second write something that's interesting for you and gives you lots of options because once your cornered in by your own story your gonna give blank on ideas and lose motivation
For the third just watch some new anime, new TV shows or even a different kind of music because sometimes they can really inspire a new idea and maybe even a new story and they can also give you some great motivation
That's all I can think of right now so sorry if it sucks
