Enter the contest. Judges can’t pick work that’s still saved on your desktop.

Selection can only operate on what was submitted. However good the file is, it takes part in nothing while it stays where you can see it, and the winners are drawn entirely from the group willing to be considered. Entering is not a claim that you deserve to win; it is a request to be included in the count.

Find one open call this month and submit whatever is closest to ready. Accept that you will probably not place, and enter anyway, since the habit matters more than any single result. Keep a short list of deadlines so the decision becomes routine rather than dramatic.
