What are some stresses from being a writer? What are your responsibilities and duties?

Stresses: It’s not a steady source of income. You always worry how your books will sell, how they will be reviewed, and if people will like them. A book you wrote and are proud of might go out of print tomorrow and there’s generally nothing you can do about that. There’s a lot that is beyond your control, so you have to take it as it comes. As for responsibilities, as a professional writer, you sign contracts promising to turn in work at certain times, on certain dates. Your responsibility is to adhere to your contractual obligations. You may also consider answering fan mail and so forth a responsibility, but that’s personal.
