When I was in 2nd grade, I wanted to be a teacher. The thought of holding that red pen and bossing a bunch of kids around seemed exciting to me. In 8th grade, I wanted to be Joan Jett, singing rock songs to a crowd of screaming fans. In high school, I decided I wanted to be an accountant, crunching numbers and filing taxes all day long. By the time I took my first managerial accounting class in college, the appeal quickly faded.
