I wrote for about 10 minutes, which is better than nothing.

It's funny, I've really been struggling with the middles of stories lately, too. I've been getting about the first 1/3rd of it down, or the first 'act', and then stalling out, probably because I haven't finished anything in a while. Part of it is that I tend to write (or attempt to write) plotty gen stories, and there's behind the scenes things that I need to work out, like the villains' nefarious plans, things that I need to know but the characters/audience don't know at that point in the story. It's extremely frustrating.
