Attempting NaNoWriMo again after a few years of not even trying, has also taught me a few valuable lessons about myself as a writer:
1) I'm a slow drafter who can't write something new without rereading what I wrote yesterday.
2) I want to enjoy the process of writing and not just watch the word count grow.
3) I might sit down to write for 2 hours and end up spending 1.5 of those hours doing research.
I am okay with all of this. It's who I am as a writer and forcing myself to pump out 50k words in a month just isn't enjoyable. Even as an exercise, it would be an exercise in futility for me because I'd hate the process (probably end up hating the book I'm writing too) and would end up with a shoddy first draft I despised because writing it had been more of a chore than a pleasure. This is why I'm okay with 'failing' NaNoWriMo. Honestly, it's not really a failure at all.
NaNo has and will continue to be a great motivator, and if that's all it is to me, that's okay because I will finish this book - eventually - and I'll have enjoyed every moment of writing it.
Final word? If you're writing this November, I wish you all the best with your NaNoWriMo endeavours! Just know that it's totally okay if NaNo isn't for you and you are NOT a failure for not being able to write 50k in 30 days!
