First who or what "ningas cogon" is I have not a clue. As to changing a peoples negative attitudes, remember they are only negative because they are different to ours who assume that we have positive attitudes. It might have helped if you had mentioned just one negative attitude that the Filipino people have. I would prefer to use the word "Simple" rather than negative. Some of the simple attitudes of the Filipino's could contain some useful lessons for us so called enlightened people.
