We are so programmed from our childhood to follow norms, conform to conventions that we never realize that we unconsiously mould ourselves to be an accepted member of the "society". No doubt all these rules and regulations are very essential but we must understand that these are not supreme. The fear of questioning the system weighs so heavily on the mind that the very idea of violating it or non conforming to it doesnt even occur.
There would be no change if there were nobody who dare to think beyond the societal cocoon. They are the Radicals. The people who dont give a damn about the ridicule, the non belief and the lack of enthusiasm and encouragement from the weak and the lazy and the foolish around them.
