Go out and buy yourself a $1 spiral notebook!! First I like to write down all of my ideas, then I make a plot map. So exposition, rising, climax, falling and resolution. That way I know where the story has to go.
Then I write out the plots/scene for the first 5-10 episodes. I try to go as far as I can until
I’m out of ideas. You can even go as far as plotting all your chapters. I just can’t be that structured or it messes with my writing flow😅
