I am experiencing something not completely new and yet uncommon.

Desidre for greater knowledge; for every possible piece of knowledge man can have. Especially if it doesn't belong to my specific field.

There is a sick joy in suggesting a better word for a translation about chemistry, and a sick displeasure in noticing that after all, I don't know exactly how brain works.

For five years of high school I've been pampered with the idea of the "absolute man" who could master every knowledge. Now, I want more.

Therefore, I am going to study some more right now.
