It’s a sad thing how many people feel that a privilege of education and knowledge, in general, is the “right” to feel that they are “so much better” than others. And they feel the need to point it out.
Education shouldn’t make one elitist or arrogant. Actually, the more educated you are, the more you realize how little you know, thus, the more you should be humble and patient.
The more great you think of yourself, no matter how brilliant you are, the less people will think of you.
