I think a physical notebook with dividers for different sections works well. And always date your notes so you know when you made them. It's also helpful to have a separate section for your ideas and inspirations related to the novel.
I'd start by categorizing your ideas based on characters, plotlines, and settings. Then, create a timeline or flowchart to see how everything fits together.
There were a total of 16 official notes. Among them, the Chongqing edition of "Official Notes" was divided into two volumes, including the contents of chapters 1-16 of "Official Notes". This work was written by the author Zhang Kai in three years.
First, you can sort them by series. Put all the books from the same series together. Then, alphabetize them by the title or the author's last name. You can also organize them based on the genre, like putting all the superhero graphic novels in one section and the horror ones in another.
Start by having a clear idea of the beginning, middle, and end. Know your main characters and their goals. Then, build a plot that leads to a satisfying conclusion.
