An interesting read. I'm not sure if the key factor is school itself. IMO it is education, whether via traditional school or through self-teaching, that makes all the difference in life. Being taught to think is what is important.

I think so too.
Education is power of knowledge on so many different and overlapping subjects and therefore the layers of life. The more educated you are, the more you know how to deal with life's struggles regarding biology, nutrition, health, economy and social effects of behaviours and so on. Understanding reduces stress. Knowledge reduces fear and so on. The list is endless.
