There isn't just one path.
There are many paths. Many ways to tell a story, many ways to revise it, many ways to publish it.
Someone else's path may not work for you.
It can be frustrating to follow exactly the same steps used by someone else, and yet fail to produce that killer novel, or get snapped up by an agent, or rake in self-publishing millions, or nab a slot on the evening talk shows.
Writing and publishing aren't recipes or scientific formulas. There are certain basic guidelines that are helpful (be professional, care about your work, do your homework, keep an open mind), but there's no guarantee that following steps A + B will produce outcome C.
There's more than one way to handle this gig we call writing. Your path doesn't have to look like anyone else's--and chances are, it won't.
