THERE is nothing wrong with immersing oneself in culture and arts. If man had just sticked to manual labor and worked only with the goal of basic survival, we wouldn't have the likes of Hidalgo, da Vinci, Dickens, Kipling, Mozart and Bach. I believe that every man's goal should be to excel in all line of human endeavor. Nowadays, however, getting by and making a living is quite hard. One must be practical if one wishes to survive these changing times. Sometimes, a part-time job is not enough.
I am not saying that one should completely turn one's back to the arts or the other. Having a job that enables one to put bread on the table and being able to pursue art for art's sake is not mutually exclusive. However, in order to enjoy both, one must work extra hard.

I guess, it is the same way with academics. If I want to engage myself in extracurricular activities, if I want to pursue other interests, then I must be first be able to address the demands of my studies. Hence, be more attentive in class, read lessons in advance, study more efficiently and effectively and minimize lost time. It's the price I have to pay. No pain, no gain, eh?
