It's stressful, everyday it's a new challenge to "outsmart" other students, as my professors say, "school is a competition on who could be more successful." Let's not forget what my other professor says, "school is practice for jail." As I get older school gets more depressing, my opinion at least.
Although I'm not such a fan of school because it's so stressful and there are so many judge mental people around, school is beneficial and will help in the future (if one does well of course). However, there are those who don't do well in school and still get a good job so I mean.. it depends really. Overall, school is beneficial and you learn a lot of new things. But... the things you learn goes down the drain after a few years lol. (For me otherwise, I hardly remember what I learned about in middle school :P)
In organizations especially in the military, the one who gives the order usually comes from the top position. It is transferred from the next to the highest position and passed until it reaches the lowest in rank.
