The first rule of writing.... write! You can't edit a blank page, but you can edit words, sentences, paragraphs, and pages as long as you get something, anything on paper.
The second rule of writing.... read! Of course, every writer should be reading as much as he or she can anyway, but it's never more important to read while you're in the middle of a project to get out of your own head and into someone else's. This way you can still enjoy words without the pressure and you'll be honing your craft.
And lastly, you need a tribe. The community at NaNoWriMo provides just that. You'll be able to post some of your writing to receive feedback and support and that's a critical step in the process. Writing may be a solitary practice, but it doesn't have to be done all alone.
