How do you write a book?

If you have or haven't written a book, I'd like to hear your methods.

How do you take story ideas and complete them?

>brainstorm
>write (effort -> results)
>edit (patiently)
>an ending creates conditions, like a math equation solved backwards
>ask for help
>meme on the normies
>tell emotions through reactions
>tell motivations through actions

Will add as we go, thank you.

You can practice the craft in every post here. Some people suggest not to tell a story but describe the actions that reveal inner motivations. You can get very experimental shifting from one point of view to any of a number of others within the same narrative. Within this communication of words and letter, there is you, the reader, me the writer, any characters we choose to introduce within the narrative and several meta points of view that exist or develop as the story develops. Each new character has internal conflicts and dialogues and stories composing the universe of his or her motivation. How deep does a story delve into all those details. Are characters a means to an end or plot devices or should they all be developed in depth so each emotion each interaction is understood complexly. A character could take a book off the shelf as simply as that. Or the character could hesitate, run their fingers along the spine remember a conversation from long ago, sigh and take a drink of wine. Elaborations of detail in action can develop the complexity of the internal emotional states of the characters, introducing new plot points or new characters within the internal narrative of their story.

Letters, sentences, paragraphs, chapters, book. You got this.

start at the end and figure out how you got there....blocking and blocking some more...make sure all the dates align times align

A professional novelist once told me the difference between a professional novelist and an amateur writer that dreams about one day becoming a professional novelist, is that a professional novelist spends his days writing novels.

I honestly think this is the only advice you need.
