#writing process

I'm working on a new story and I've been thinking, do most writers know how their story is going to end before they start? I don't, and it's kinda frustrating. I feel like I'm just making it up as I go along. Is that normal? I've heard some people swear by outlining, but that's never really worked for me. I just start writing and see where it takes me. Anyone else do it this way?
