This article makes some fantastic points. I find it sad that we force ourselves to have outwardly facing purpose to almost everything we do. Even if purposeless walking has the internal reason of more thought and creativity, we can't do that because there seems to be an over arching need to have an outward requirement to all activity (complete a project, get more exercise, fulfil some need, etc). This was driven home…
Is this common in whatever country you're in? If this happened where I went to school, there'd be words at the PTA meeting. Your principal is some kind of control freak. It doesn't sound normal at all.
That being said, I can say many of the people in my peer group did conform to these standards and did become very successful. I can point at handfuls of my friends and acquaintances who went to school at MIT, Harvard, Stanford, and many other highly rated schools on full ride scholarships. A number of them have successful careers in medicine, law, politics and even professional sports. So, I guess the proof is in the pudding, it does work.
No one ever spoke up at a PTA meeting because parents wanted their kids to succeed, and the thought process goes that if they followed the program, they would succeed.
Of course, we won't talk about the suicide rate at my high school...
