One little reminder that I repeat to myself every November: you do not have to do NaNoWriMo. November is a busy month. You have school and work and holidays to worry about. 50,000 is a lot of words, and a long story DOES NOT EQUAL A GOOD STORY.
You work differently than other writers. NaNo doesn’t fit your style. It’s okay to not write every day this month.
Put health and school first.
