Lo key, this is my go to for everything when I'm posting:
Whether it's for story planning, motivation, story structure, making a story move forward, etc -- the one thing that hasn't failed me yet has been making music playlists for my stories.
I am one of those people who can see entire music videos when listening to music, and I know I'm not the only person who does this.So I use that to my advance. I create a playlist with music that I personally feel fit my story, my characters, and their motivations. Then, I usually create entire scenes, if not concepts, through the music.
I piece everything together later. Lemme tell you -- I've completely two comic scripts that way. Two very long comic scripts.
It can be a messy method and might not work for everyone XD But give it a light try and see how it works out for you
