A Reading Request Please
Yes, you will succeed. I'm not getting that this novel is a complete work of fiction, but something based on your own life or that of someone you know. This story will be of great value to people, and may even become a movie down the track.
I also get that going through the usual publishing channels may not bring the success you're after. Have you thought of self publishing? I realise that involves cash input from you in the first instance, but I think this may be the way to go for you. That way, your book will be published on your terms without too much interference or adjustment from well-meaning editors, etc. This book needs to be out there pretty much how it's been written.
I see you reaping the benefits of this within two to three years (seems to be a popular timeline for things these days!)
I sure hope this helps you some. Have a good day
