How to write a novel

First think of a good plot

Record the idea, then drop it when your mood is on tho

I think that all novelists begin with a 'framework' or what is called a plot. Just about every story there is deals with a problem that arises and consists of the way in which it is resolved but first of all you have to describe the situation. A short story is usually quite simple. You introduce one or more characters, set the scene, describe the problem which needs resolving and tell how it is resolved. A novel may be longer and more complicated and may involve more than one problem. If you feel that you have a novel in you, start by writing a very rough outline of the story and a paragraph or so about the main characters. If you don't know your characters intimately - their good points and bad points and their likes and dislikes, you won't be able to write about them successfully. It would be quite unusual for a writer to always begin at the beginning and write non-stop until they reach the end. Most find that their work is unsatisfactory at some point and have to rewrite whole sections of it. Quite a few get stuck half way, put the novel in a drawer and come back to it much later. It's a good idea to ask yourself before you do anything else: "Why do I want to write a novel?" and to be brutally honest when it comes to the answers! Is is just because you feel that a novel is better than a short story or that you want to see your name on the jacket of a book in a bookshop?

write a theme and a frame

Yes first we need a plot

No idea my friend. I don't have any experience with writing novels lol.

@udinwardoyo maybe you can make novel outlines first, then write your idea according to it.
