Outline? Pshaw

I started a new story - got a first chapter out, and realized once again that I have no ability whatsoever to outline a story in advance. Even with this, the first chapter of the story ended differently than I had thought it would when I started. The trouble is, I just don't stick with my outlines or original ideas at all. As I write, I tend to adjust a lot, often changing major story lines as I go. This can result in me going back and making changes along the way, but I see nothing wrong with that. Luckily, Caitie, the one person I let read as I go, is always with me so I can tell her of any changes I might make in earlier chapters as she reads something that comes later.

Caitie tells me that once I get established, agents and publishers may want advanced stories. This TERRIFIES me -- I have NEVER (with the exception of stories based on real events) outlined and stuck with an idea all the way through. The process of creation for me IS the writing, not the pre-writing, so I have no idea what I'd do if I get put into that position.

Hopefully I'm never faced with that...
