Learn the words of wisdom uttered by the wise and apply them in your own life. Live them - but do not a make a show of reciting them, for he who repeats what he does not understand is no better than an ass loaded with books.
Herein is the evil of ignorance, that he who is neither good nor wise is nevertheless satisfied with himself: he had no desire for that of which he feels no want.
With the realization of ones own potential and self-confidence in ones ability, one can build a better world. According to my own experience, self-confidence is very important. That sort of confidence is not a blind one; it is an awareness of ones own potential. On that basis, human beings can transform themselves by increasing the good qualities and reducing the negative qualities.
