I create characters first then put them into a situation.
Definitely know that feeling
Good characters seem to write themselves!
Though sometimes I don't have even a vague idea of an ending, and as I write the ending fleshes itself out perfectly. Beginnings and endings are a couple of the the hardest parts of storytelling for me, I find if I get an ending in mind I can end up set on it and while I know what's going to happen.. I write myself into a corner. If that makes sense. >_>; -is weird-
