And I don't mean to limit "ambition" here to length, or plottiness, or other sorts of craziness. I think there are lots of ways to write ambitiously and many different points at which it becomes clear that's what you're doing (whether you saddle yourself with a decidedly ambitious idea, or you only reason five months after the fact how ambitious your 100 word fic was), and I would like to remind myself to reach for all of them.
I would like to write new things--pairings, characters I haven't written before, tropes--but also reimagine old ones. I want to take my characterizations into new dimensions and revisit old ones. I would like to write some plot things, but also imagistic things, and experimental things, and pulpy solid read-me things. I want to engage canon in a way that does more than just sit beside it, or wander bizarrely away from it. I want to write all sorts of different things, and through this come into my space as a writer--which is a space I think I've timeshared a bit this year, but I don't really have a mortgage or anything.
And I want to find out if understanding those things as either ambitious or unambitious ends up just fucking things up! Because I can see the potential for that, too.
What are your writerly/artistic resolutions for the new year? Or just plain old resolutions, really. My plain old resolution is to buy less cheese, and therefore eat less cheese. Because cheese is $$$!!
