Week 5 do now

Is the principal the most important person in a school?
                                                                                                                                                 I think that the principal is not because he comes in every 4 weeks and says some speech that is supposed to boost others' motivation. But there are other people in the school who are just invisible but they are doing big things for the school like food or stationary. There are so many people that did a lot for the school and don't get noticed.
