why and what should we learn

i know people here some just have a regular job , and some just like me , still study .

i believe that everyone almost , had a same idea with me , '' why should we learn ? '' when ur a student . this question is mystery , ive been ask some people , some are teachers , some are friends , teachers just always said '' we learn for a great school , and a great future also ''  but when i asked back '' why should we learn for a great school , and a great future ? '' they stop a while and said '' for life '' but when i asked back , they just said '' i dont know either ''   

and what should we learn ? people just said , we learn for knowledge , any kind of .

a long time ago , i thought we learn for knowledge too , but now , i think we may learn for joys , after we got  knowledges , we got joys also .

but i had another idea , we learn for dead , it sound awful , but we learn for dead , arent we ? we learn for a great school ,  a great future  , and life , but after that , coz we learn for dead . i know micheal jackson just died , i m so sorry for hearing this , but just like everyone , everyone would die . that's the same goal of every person in the world , died .

so , what do u think about why and what should we learn ?

If I'll ask this question to myself, why should I learn, simply, if I hadn't learn, I wouldn't know anything about me, I'll be in dark, I mean dark about knowledge; because when you have knowledge and education, they light your way, confusion will disappear. It is right we learn for future and for life, for you too, just compare yourself with someone in your age that didn't have a chance to learn or educate, you'll absolutely see the difference. What should we learn, just say this "I can learn anything", don't limit yourself only on one thing, if I choose to learn a certain knowledge, it doesn't mean that I'll not learn other knowledge.
