The Wait.

Honestly the worst thing about writing sometimes is when you finish your side of things, and you are just waiting for either the right time to release your work.

At the very least it gives me more time to work on my current novella to make it the best version possible while also letting me work on my old series to bring them better quality.

Release times windows/etc are rather important and missing one or messing it up can really bring down the momentum of a good day.
