Discovery Writing: Is it for you?

I know people who have said they never use outlines, but I guess I always assumed this was an exaggeration. I thought that what they meant was that they didn’t have pages of bullet points and chapter breakdowns like I use. I was wrong; some people go in with very little prior planning and still manage to have a working story at the end. It seems magical to me, but it does happen. However, is it right for you?
