I have tweeted this before, but it’s worth saying this in a blog post and reiterating it once again for good measure:
Be wary of anyone who tells you there’s only one way to go about the publishing process.
There are as many ways to find success writing books as there are books. Anyone who tells you that the only right way is traditional publishing or self-publishing or with an agent or without an agent is probably simply telling you what has worked for them and projecting that experience onto you. Either that or they’re trying to sell you something.
There’s only one person who knows what’s best for your manuscript: You.
Do your research, follow your gut, figure out what works best for you. And if the first thing doesn’t work try something else. And if that doesn’t work try a third way.
There’s no map to finding success with books. There’s just a constant journey.
