“When people make changes in their lives in a certain area, they may start by changing the way they talk about that subject, how they act about it, their attitude toward it, or an underlying decision concerning it.” –Jean Illsley Clarke
How you view yourself will affect how seriously you take your desire to write, which will profoundly affect your ability to be a writer.
When someone asks what you do, how do you reply? Do you offer your title at your day job? Or do you say “I am a writer”? If it’s the former, it’s time to come out of the closet and claim the identity. As long as your writer identity is in the closet, your commitment to making time to write, making the effort when inspiration is lacking, or submitting your writing somewhere will be less than what it could be.
