After more than 200 years since Jean Jacques Rousseau uttered the aforementioned saying, I feel that nowadays we are in the same situation as then. There are strict social limits to live by and few are encouraged to do more or to embrace their calling.
My social experience until now has brought me to the conclusion that it is more important to have an opinion of my own regarding certain things than to "inherit" it from others. I met people who were so much indulged in living by the others' life standards that they did not even realize how miserable they were. And how could they be aware of that when all of their lives they were "helped" to feel anything except their inner feelings, needs and aspirations?
It is the same in Plato's Allegory of the Cave, only if one wants, can one come out in the sun and see the shapes as they really are.
I think that every one of us should engage once in a while in "absolute subjectivity" and try to understand who she/ he really is, the direction she/ he needs to take in order to be happy (so that the others could be happy. I always thought that happiness occurs due to a chain reaction. It cannot come out of nowhere. It can only be felt, lived and "transmitted" to the others around). I think this is how we should raise the young generation. I reckon this is the basic knowledge the youngsters should have when they set out on the journey of life.
