What we all do throughout our whole lives (I mean most of us) – we study. Schools, colleges, universities, additional education, extra curriculum activities… All these things we do are transmitted in our genes from our parents. We must study. We should learn the stuff. We ought to be prospective and get a good career…Wait… I think here is the main point of our “thirst for knowledge”, here’s the essence of our constant devouring information. We just need to have a stable respected and successful career.
