Theatre teaches you the importance of rules, a concept that's valued in any organization. Your work in college theatre will show that you have the ability to grasp complex matters in a short period of time, a highly-valued trait to employers. If you don't listen, you're likely to make some major error that will damage the production. Listening is a skill for any job. In theatre you discover that a successful production requires contributions from everybody who's involved.
