So, I was thinking I might be going overboard (Or even winging it too much in some cases) with the importance of pre-planning my characters, so I was wondering how everyone else develops their characters. Do you like detailing a lot of backstory? How about Character Arcs? Relationships? How far do you go before you write your story? I often find my characters are nebulous, and I can't quite pin down them down to something fleshed out. When I finish a short story, the characters actually turn out pretty well, but I don't put a lot of thought into them and they develop as I write. For my novel, I feel like if I don't go overboard on detailing them, they will suck, but I can't seem to flesh them out too deep, given my seat-of-the-pants style of writing.
