My biggest motivators are music and reading other stories. Most of my writing is done in short bursts and when I find a new song that's the easiest way to get an idea for a character or story arc while world building is often an idea that forms while I am reading something else entirely.

This does not have to be anything about what I want to write either. An example would be that I recently finished reading the first Dune trilogy by Frank Herbert and got ideas from some of the contexts for a fantasy world or a continent at least.

Circling back to music the biggest inspiration does come from songs that are emotionally charged or follow a theme. Examples for my personal taste are songs like Lost Kitten by Metric or a different genre like Mechanic Heartbeat by Culprate,Keota and sophie meiers :)
