WTF! Get back on track dammit!

So I've fallen off the writing bandwagon lately.

Reasons why?
1. Xmas gift making [still got more to do tonight]
2. Costume making [spats and such]
3. Trying to figure out the ending before I get there.

Of all the reasons, number three has my writing practically at a stand still. Like I've said before, it's because the end result is due to a series of events...and I want to plan them so that they make sense. But there are some that for the life of me I can't figure out.

So I'm stuck.

But I really need to get back in the game. I want to finish the damn thing before Jan 1st--hell--I want to finish it. Period.
Part of me says just write whatever ending comes to you and then fix it in post. While another part, the perfectionist, wants to know every last detail before I can write.

This is problematic. I need to solve this ASAP if I want to have this stuff written before I get home on Friday.

Help!
