In filmmaking, scene lengths control rhythm, activity within it controls tempo.
Shorten/quicken as you build to climaxes. Let them breathe. Story dictates the pacing.
Research: Dig deeper than Wikipedia. Inspiration is literally all around you.
Books, shows, videos, of course, but also your barista at the coffee shop, your grandmother, the people you walk by downtown, etc.
Immerse yourself in living life, and truths will find you.
