As a writer, there are going to be days when you don't want to write. In fact, you're going to want to do anything except write. You're going to sit at your computer and open Firefox, check Facebook, close Firefox, sigh, and open Firefox again to check your Facebook because, hey, you never know, someone, somewhere, may have said something interesting in the 30 seconds you've been away.
The most interesting comment on your status cannot compare with what you're about to create.
You are a writer, an artist, a creative being with a creative soul. Creating things is such a part of your being that when you don't, there's something wrong with you, with your world, with the atmosphere. You were made to create.
But you don't understand! I'm sick of my MC! And my plot has so more holes than Swiss cheese!
...or, I have to edit! And I haaaaaaaaate it! It's so. boring. I'm going to die with its boringness, die of boredom. Whatever.
I understand. All too well, I understand. (Editing sucks. I know.) But just take a deep breath. Because if you log into Facebook one more time, you'll be lost forever. You have to create, need it like chocolate. And right now, you should be making up new worlds with new voices and new stories that the world has never before seen.
Yeah, you may open up Word and stare at it. And stare at it some more. And wonder how in the world you'll ever finish the monumental editing task ahead of you. Because it's really big, and you hate editing. But then, you know you have to edit the thing, because you made a promise to yourself (and told all your friends and family and blogging buddies) that you would query it. And you're not going to be one of those people that query before they're ready, right?
So go write. It's November - go work on your NaNo novel where you can write crap and it's okay. But go write something, you awesome creative soul! It's what you're meant to do. Facebook will still be there when you emerge from the creative cave, still bearing a little bit of the sparkle-dust that sometimes rubs off on those who stay long.
