By the way, regarding idealism. I've catched myself admiring students who e.g. work on school stuff during their lunch time. Although I've many opposite arguments why my way of spending time is far better- I talk with people and have pleasure, I don't need to study during my free time in order to get good grades, I simply study during another time than them, etc.-, I still doubt if it'd better to pursue "fullfilling your potential" in an Aristotelian manner. Yet I also recognize that I'm far too young to judge it, because I simply can't see the implication of studying during your lunch time in the long run. What do you think on that?
Only one I have time to comment on now is this one: As usual with Aristotle I think he's sounding grand without being suspicous. What IS your potential? Just like "what IS happiness?" Aristotle evades giving an answer to those questions, or simply hints that you should follow virtue or what noble Athenians do. I think Epicurus might say that your "potential" is not being the best student you can be, but living a happy life based on what is pleasurable to you. Now study might in fact be pleasurable, in the way that Epicurus said he liked to pursue the study of nature. But if you're studying just to get the highest grades, or out of some duty or abstract goal that you can't really even identify, that seems very shortsighted to me.
