Well it was related to the thread I posted last time and people seemed to prefer the isekai one so I decided I'll write that one since I had got a better idea on what to do now
There is another reason. If you write 50 chapters, and have zero feedback or interested readers, you will, probably, be more disheartened. Since you've spent more time on writing it all. Meanwhile 20 is an okay number to either abandon the story and start something new, or keep going.
Oh don't worry I just want to write the story because I feel like it and not for some grand thing like being famous or anything. Even if I do have like 60 chaps saved up I'll still release it in a decent schedule instead of putting it all out like some sort of self inserted deadline I suppose
You don't want to bulk upload here, on SH. Upload more than one chapter in a brief period of time, and your story will be hidden for a day. So release one chapter a day, or two chapters, but spread the releases of multiple chapters. Wait for at least three, maybe four hours.
I know you don't need it now, but I want to warn you anyway.
