This is a late congratulations to those who participated in NaNoWriMo 2010.
If you finished your draft, AWESOME JOB! COOKIES FOR YOU!!
If you stopped halfway through: DON'T GIVE UP NOW! You can still finish!!!
If you completely and utterly failed: KEEP GOING! Continue your NaNo experience into December and January! (January might be best, but I don't know your own personal schedules, so it could very well not be.)
And if you're unsure of what to do with your finished manuscript, there is a plethora of things you can do. My personal favorite is printing out the entire thing and dropping it on a table. The thump of the landing papers is very satisfying no matter how much you think it sucks. The second thing would be to take a small break and start editing it. It will call for a lot of rewriting of the scenes and reworking of dialogue and character development, but that's what writing is all about. The magic happens with revisions, I say. You can also forget you wrote the thing entirely, but that's completely your choice. But why waste the idea and the month, you know?
Whatever you choose, I hope you succeed in completing that task. Good luck on revisions and don't forget to be awesome.
