When you finish a writing project, there is always the danger of falling into a black hole.
The black hole is the space that opens up after a project is done. We fill it with the responsibilities we've put off, like housework, visiting friends, and other small tasks.
The danger is we can lose our creative focus because of it. We obsess over the busy work and forget to spend time on the work that matters to us.
The ideal plan is to continue working. Not a lot, but enough to keep the engine running at a light pace. Show up on the page and do work. Write a few minutes or pages until you're ready to do the next big thing.
Completing a project is a great accomplishment, but learning what to do next is just as important.
