(b) Making it past the dreaded mid-month slump
(c) Finishing! and,
(d) Having fun while doing it all!
In case you're not familiar with NaNoWriMo and AcWriMo, they're terrific monthlong writing challenges that support the basic principles of nonperfectionism. You seek to write a lot (50,000 words over the course of the month, in the case of NaNoWriMo), focusing on quantity not quality. The NaNoWriMo site provides tools for monitoring your progress and celebrating your successes, plus wonderful international and local communities of support.
One of my favorite things about NaNoWriMo is that they've created a section for "NaNoWriMo Rebels," who WILL NOT FOLLOW THE RULES. They really do want to get everyone writing!
