Self Realization is the first step towards greatness in life which includes nation's and continents.
Countries like China, the United States of America, the United kingdom, Russia, China, Singapore, Qater, United Arab Emirates etc has all understand this fact that, the only way to make reasonable progress is self Realization. You can't see a Chinese, American, United States of America, French, Singapore, Russia and Chinese citizens claiming belonging to other races.
All the nation's that are leading has come to the fact that they can't make any reasonable progress without thinking inward. Today if you look at third world nation's such as Africa you will find out that they don't think and do things like their ancestors .
For some reason, the way you draw conclusions feels very superficial and overlooks many factors. People or nations change due to awareness. Identity awareness does not automatically lead to development awareness, sometimes society begin to realize the need for change from crisis, external pressure, economic necessity and recognition on their limitation. Frankly speaking, awareness alone even for a great nations can not create development if it can't be translated in to real aplicable vision by eddective leadership, supported by capable institution, STEM based education and productive human capital and many factor.
So, i surely said catalyst of personal and national development are the ability to recognize what actually we lack, the wisdom and strong desire to learn from other and strong institutional capacity to turn knowledge in to well targeted change. Self realization only show who we are. But awareness can show what wrong with us and what we supposed to be. We know the word of adaptability which making us realize that sometimes, old ways are no longer sufficient to face the future.
