1. Set a manageable goal.
This seems very straightforward, but it's actually hard to do. I really want to bang out an entire novel, but that's very unrealistic and overwhelming to me. That's why I set a lower goal that I'm pretty sure to complete. (Hey, a little progress is still progress!)
2. Join an epic cabin!
Find people who will inspire and motivate you. Find the people who will word sprint with you at those times when you really don't feel like writing.
3. Write. Every. Day.
Seems like a no-brainer, but some nights you will just want to go to bed. Tell yourself that you can't go to sleep until you write your allotted number of words for today. Remember that once you let it slide by once, it's easier to let days go by where you don't touch your WIP. Discipline is key.
4. Save a little time to refuel.
How to you fill yourself up creatively? Save some time for reading, watching a movie (don't get too sucked into electronics, though), and reading your Bible. Don't completely burn yourself out!
5. Sometimes the words will flow (and actually sound decent!) and sometimes they won't.
During those times when you know you're using "said" way too much and start every single paragraph with your MC's name, KEEP GOING. You can fix that later. That's what editing is for.
6. Remember that Camp NaNoWriMo isn't the most important thing in the world.
(Forget this tip if you have an actual deadline. Then it is the most important thing.). I have to remember this too. Especially if you're in school, keep Camp NaNoWriMo as a higher priority extracurricular activity. If school is super demanding right now, consider lowering your goal. There's no shame in lowering your goal if you have a lot of very important things happening. Don't kill yourself over something that's supposed to be fun/productive. (Writing probably isn't your job yet, even though you're supposed to consider it your job. Sometimes it's okay to treat it like a hobby.)
