Indiana Jones said " Knowledge is Treasure " at the end of the movie.
Does not means that a person study till master or honour has a good knowledge. A good knowledge is from the understanding of each book or subject that a person study. A high scorer master holder can have low knowledge as he may memories all the theory without absorbing it. Alot of people went through their studies just to get a certificate without understanding the theory of the subjects. Thus, they have a difficulty when go to society to work. I have met quite few of these people. They are holding a master degree but they did not know how to do the assignment that the employer passed to her and they still getting high salary.
In the other case, I have a ex colleague which is a Indian. He do not have a diploma or degree certificate. And he always act like he is really smart but my ex boss likes him since he knows when to sweet talk. He always wear or act like he is high professional ! If he done wrong anything, he will act blur or push to the other colleague. When come to difficult task, he will find excuse to push away the assignment or tell boss he is really busy. Ya, he always act like he is really busy. Like Real ! Only boss believe him. This type of example is no certificate and no knowledge but act act alot lor ! Hope the boss realise his capabability asap or else alot of ex colleague left because of him. Wake up bosses ! Sweet talk is not equal to knowledge !
