I haven't personally spent the time and money to find out, so I can't say with one hundred percent certainty that all of those offers are complete horseshit, but I can say that I've done pretty well for myself so far without any of them.

Success as a self-published author, in my experience, has come by focusing on three main things.

1. Writing books that people want to read.

2. Putting those books in a package that lets the people who want to read them know, as immediately as possible, that they want to read them.

3. Getting as many of those people as possible to know that the books they don't yet know that they want to read even exist.

If that all sounds very obvious, please take into consideration that you're the one who clicked on a link titled "The Secrets To Success In Self-Publishing". That title should have been like a giant warning sign that you're approaching Mt. Bullshit, and it's about to blow.

There are no secrets.

All those "masterclasses" and gimmicks people are trying to sell you on Facebook? Without the requisite time having been spent learning how to tell a story by reading and writing and more reading and more writing, all of that shit might as well be a pipe and a vintage typewriter for all the good it's going to do you writing and selling books.
