Let me tell you a secret.
If you want to turn back, you can.
If you want to go forward, you can.
This is completely up to you. Yet, but I want you to know that there is no fun in a turnback. But here is what you will inherit if you turnback.
You will earn something that is worse than that rejection: REGRET.
It is one thing to get rejected over a work that you completed, edited and shopped.
It is another to allow the fear to choke the creative out of you.
A completed work can be reshopped, edited again, and submitted–but an incomplete work cannot be.
What is it that you desire to do writer?
If you go forward–there is a way forward. If you turnback, there is no way forward…by your own hand.
