For me, I started writing because I wanted to write what i was interested in. don't get me wrong lots of people write something that they have an interest with and then just discontinue halfway through, but for me, pick like a story idea that you wanna read, but no one's made a story for it yet, so now, you just wanna tell a story idea that you like and haven't seen. that's one of the things i get my dedication from. just think of something u really like, like RWBY, or JJBA, or Naruto, literally anything. and if you start to feel like u dont have passion for it anymore, then that's fine, u can just relax without having to worry about updating your book, and then when u feel like it, u can always continue it. sorry if my ramblings make no goddamn sense
