When I started writing my first novel, I jumped in with both feet and never looked back. I had the idea laid out in my head. Not each scene or chapter mind you, or even all the characters, or the setting, or the antagonist, or three acts, or any research on the technology that would eventually become part of the central plot. The ending, you ask? No, hadn't really given that much thought either.
But hey, I did know who the protagonist would be, but no, I hadn't really flesh out his background on paper or anything. He was going to be cool though. I knew that. He wasn't going to be like all the other hero's out there. He was going to be different, something unusual. There was no rush, I could wait to get to him. After all, he wasn't going to appear in the book until at least chapter seven. So, what's the rush to figure out what made him who he is?
