Write a first person “Because” story. Start every line with “Because”.
List the reasons why a character worries, doubts.. etc. Or why the character loves, envies or hates.
For example. “Because I found him with in the kitchen at 6:00AM, looking at the clock. Because my mother died in the ocean on the nicest day of the year… Because she has gold-tinted eyes, just like the ones he paints.”
You can have your character lie if you want to. You can edit them out later.
