The challenge; Complete 50,000 words in the month of November. Don't worry it can be done without panic.
First: Check out all the good stuff on the official NANOWRIMO website; https://nanowrimo.org/ They've got lots of inspiration and things to get you writing.
Second: Plot your NANO attack. I don't mean plot your novel but you can if you're a plotter (not a pantser?) I mean plot your work time. Think of your life and where you can get uninterrupted time to write. I once got up a half hour early to win NANO. That book is now up on Amazon: Soul Mates A Different Kind of Love Story At that time in my life I was in work by 8:30 am so I got up at 6:30 am and wrote for a half hour to an hour depending on how the story was moving. But it was getting up at that hour that gave me time to dedicate to my goals.
So plot out your writing time. Make it a time when you can have some uninterrupted writing time. I chose morning before the family woke up but if you're more of a night owl go for it. What's your perfect time?
Third: Assemble your space. There's nothing worse than having to get up and clear dishes or toys off your table before getting to work. Truthfully, that has tanked my writing sessions more often than not. Got a desk? A table you can squeeze into a corner or any place you get on your laptop, tablet or however you write and be set to go when you sit down. Make it yours, make it comfortable and make it a place you want to go.
Fourth: Get down the bones. Write your story. Get up & go to your special place and write. Decide if you're a plotter or a pantser. This is probably something you already know if you're been writing a while but the one thing to know is you don't have to be exactly one or the other. You can combine it.
I get an idea and first write the blurb of the idea. You know that first inkling of a story that comes to you? Not the whole story but maybe a bit of the direction you're going. The blurb is kind of like that thing on the back of the book or in the book description that gives you a bit of the bones of the story. It doesn't have to be a lot just enough for you. If you like to plot then write down that outline. You don't have to follow it but if it gets you going, then great. If not, then change it as you go. The writing rules at this point are your rules.
Fifth: Tell people. Join a NANOWRIMO group in your area. Find other writers either in person or online for encouragement and to help keep the NANO alive in your vision. Life gets busy and sometimes our goals fall to the sidelines when that happens. Connecting with others with the same goal can keep you on track.
GO NANO! You've got this!
