I am a stubborn person.
Most people would not call me stubborn. I try to be as polite as possible and when I refuse to budge on something, it often takes them by surprise.
I think stubbornness is a good quality to have, both as a person and as a writer. As a person, being stubborn means you stand up for yourself and refuse to give into others. Similarly, as a writer, being stubborn helps you to stand firm in your writing, allowing you defend the integrity of a piece.
There will always be someone who disagrees with you, who tries to bully you, and who tries to change your writing in a way that makes you hesitate. As difficult as it may be, when you come across that person, you have to show your stubborn side. At the end of the day, you are the only one able to fully, one-hundred percent look out for yourself.
