Gabe Sonnier's may be the principal at Port Barre Elementary in Port Barre, Louisiana, but 30 years ago he started out in an entirely different role: school janitor. CBS News reports that at the age of 39 he decided to go back to college to be a teacher. "Whenever he wasn’t cleaning classrooms, he was studying in them. He got his teaching degree and, shortly after, his first teaching job. Then came the Master's of Science and Education." Now he's principal--and he still cleans his own office.
