An author isn't just a person who writes books, poems, stories, etc. An author is a god, a creator, someone who is not to be tampered with because they need to exercise their minds at all times. They are regular people who struggle through life every day and delve deep into their creations to escape from life. Knowing they can create an entirely different world, or control these people who do not exist make them feel stronger, better about themselves.
A person who will go crazy if they can't figure out what to write next. Writer's block is like a hundred-foot tall wall that extends forever on either side that no one can scale; it won't go down until the writer is in the right mindset, or has some type of inspiration.
And author is strong because they have no choice but to be - for the publicity, the criticism likely to come, the obstacles they have to face along the writing process, etc.
They are, most likely, the heroes that have kept us all happy because they write books to keep us entertained.
She's written an amazing book! What a great author.
