Being a free thinker is almost impossible as it appears to be to a common mind. But if we are determined enough, nothing is impossible. As its said above, freethinking is not the common state of mind and being common, one cannot achieve or accomplish the uncommon things. We must strive to become freethinkers as much as we can and in as many situations of life as we can. Its indeed essential, for right thinking, for right way of human evolution and for the ultimate survival of mankind.
