When you go to work in the corporate world, you're usually given a copy of your job description the moment you set foot in the door on your first day. You know immediately what is expected of you and how your performance will be judged. You also have a high degree of confidence that if you do the work assigned to you, you will receive a steady paycheck.
Unfortunately, freelance writers don't have a cut-and-dried list of duties. In fact, many of us get into trouble because we neglect a task that we weren't even aware we should have been doing.
Just for fun one day, I decided to sit down and figure how many jobs are actually encompassed in the term "freelance writer." The number was...well...interesting.
