Storytellers out there, how do you operate?
Did you master the brainstorm?
Do you take it one chapter at a time to see where it goes?
Do you wing it and let your improvisation skills shine?
I don't plot in chapters so much as in segments. I'm like... the dad in Big Fish, if you've seen the film. I tell stories about my characters as seen in key moments in their lives, rather than unwinding a straightforward tale.
I think I still have a lot to learn when it comes to brainstorming, but with that said, I enjoy my own process of doing it --which is pretty random and fun. I don't do improv, but I tend to focus on different aspect of the characters or stories as it catches my eye, so a story unwinds like the roots of a tree --thick in parts, and splitting off to finer details.
I tend to world-build and create characters, rather than tell a story straight out, but I have a lot of fun doing it. Working behind the scenes leaves me with knowledge of what will happen, and a lot of speculation, but the complete story often remains open-ended in terms of possibilities.
