You may not have thought about this but school is your current career in life. Like your parents, you leave early in the morning and have to sit through a number of "meetings" (classes), you have a lunch period and the day can be filled with emotions -- exciting, stressful, joyful or sometimes sadness. Also, sometimes you have a boss (teacher) who can be a challenge or a pleasure to "work" with. There are a lot of similarities between a job and going to school.
Alright, the big missing factor here is that you don't get paid; but look at it this way, you get a lot more vacation time than your parents!
This section of our site deals with the issues around school and the relationships you have there. You are preparing yourself for life both by building your mind but also building your body (sports) and developing relationship skills that you will use your entire life.
