Carrie Underwood was 21 years old when she auditioned for 'American Idol,' and she was no slacker prior to doing so. She took jobs as early as her freshman year of high school, which is when she worked as an attendant at a Checotah, Okla. gas station. Later, she put in time at a hotel, a pizza place and a veterinary clinic. After high school, Underwood went to Northeastern State University, where she focused on journalism. Underwood had dreams of TV news fame. Maybe that can be her retirement plan?
