We are not entitled.
Just because you've written a book, it doesn't mean you will be published. You are not entitled to be published. If you want to be published, you need to do the work that will get you there. Period.
In life, if you want something, then you get off your arse and go get it. No one said it would be easy. So why do you get all stroppy at the slightest set-back?
I've heard authors rant and rave like lunatics over the most polite of form rejections.
How dare they? My book is nothing but genius. Acquisition Editors are idiots. The publishing industry is one giant doodle-head (I stole that one from BBC's Merlin... ahem, moving on). It's everyone else's fault but my own.
Get over yourselves, people.
Granted, I've been upset at all the rejections, and I'm currently burnt out from working like hell trying to get published (but I'm resting up so I can keep at it). Never once, however, have I called anyone in the industry names. Never once did I blame anyone else but myself for my current state.
I'm not entitled to be published just because I've written a book (or 6). If my book is good. If I'm doing the work. If I persevere. If I manage to keep my head and keep writing and keep working, then I will be published.
However, I have to work to get there. A publishing opportunity isn't going to just fall in my lap.
And it's not going to fall into yours, either. So get off your arse, and do the work!
