The hardest thing I found with doing NaNoWriMo this year, well, one of the hardest things, was that I completed the story, wrote "The End" and everything, when I still had 6,000 words to write. So without that motivation to get to the end (as I had already done it), I found it really difficult to stay motivated. I think this is what has happened with Inter Vivos too - I have completed the first draft of that, but now that I have to go back and fill in some gaps, it's not as exciting anymore. I guess this is where discipline should take over, but I'm crap at making myself do stuff like this. So new resolution, I am going to write every day. I am not going to stick to a word limit per day, though I think a minimum of 50 words is doable, but I am going to add a stipulation that these words must be in the form of fiction (regardless of medium), and by that I mean does not include any planning, note taking, character notes, maps, or anything else that is not directly contributing to a short story, novel, play, etc.
Phew! And I'm going to be strict on myself.
Anyway, I am 28 years old, and have two completed first drafts under my belt. Not a bad position to be in, so long as I don't lose momentum, and I actually do something with them. I'm feeling good.
