As Chuck Wendig, my very favorite unconventional, crass, irreverent but still somehow motivational writing guy has said many times, Writer's Block Does NOT exist. (Great NaNo blog post here).
I have days when I don't want to work. Work being the food court where I served up hot dogs, or worked in the coffee bar, or the service desk helping people return stuff. Or writing. It doesn't matter... You don't want to work sometimes. That's okay.
But it's not an excuse to hide behind. If you are stuck, that's okay. Do research, write your way out of it. Or move to another part of your story and come back to it. But don't use it as an excuse.
"I can't write, I have writer's block." Um, no. You're choosing to let your situation dictate your actions.
YOU are in control of yourself. If you want to write, you will write. You might still be stuck at the end of your writing, and that happens sometimes. Research, ask questions to help figure out your problem, get help if you must. But if you use being stuck as an excuse to give up? I have no pity for you.
Sorry, but I don't. You can do this. You have the power. You are allowed to change your mind or change the story and fix your problem so it isn't a problem anymore.
I'm not saying to delete. No. Strike through. Keep that word count, you might need those words later (either for the almighty word count, or for your awesome way of putting the words in a certain order right there). But work around it. Find your way out.
Your story might be a maze... but it's not a box with no exit. Work for it, damn it! Prove to yourself you CAN do it. Because you can. *nod*
