For those who never wanted to write a book you have to talk to people called literary agents. Often times they will have to go through these massive piles of people’s work just to get to yours. Even if they get to it there will be a rather a high chance that they will not like it. This does not mean your work is bad it just means that your work does not fit in to their business model. Some people will rant about not getting published saying how some of these people may be heartless, and maybe some are.
I don’t know them personally though so I won’t judge. I just have to think to myself that they are doing what they believe are the best moves for their own businesses. Can you blame someone for trying to eke out a living? I really can’t most times so I just sign it off as they may not want it now, and try again either later in the creation process or after another round of editing.
Often times all they will see of your work is two chapters tops as well as a query letter. which essentially amounts to a lottery pick if they have an opening, and winning it if you get a contract. Nothing wrong with a little luck. You will get aggravated, maybe even full fledged angry. Just try to do something where you can pour in your frustrations before coming back refreshed with the right mindset to continue moving forward. It can be worth it if you try enough.
