As an author it is good to keep in mind that what you are creating is something special, something unique. A book can takes something that you feel is important and make it clear to others. A short story that can entertain someone during their darkest hour. A poem can show the importance of a certain moment in someones life.
As an author you never hear from all your readers, often you won’t even know when your work has effected someone else, but it is important to know that your work has made an impact on your readers. Just as other’s writing has affected you.
