Why some ppl just like to study?

had a small get-together with my course mates at mache on Sat.. yummy.. really like the mushroom soup and ginger beer.. always buy that when I eat there..

then heard from a friend that she going to graduate one sem later than us.. to fulfil the modules requirement for a double major.. yah.. she's doing a double major.. Chem and life sci.. yah.. impressive right.. and that's not all.. she's going to do medicine after graduating at the medicine graduate school.. it will take her another 5 years to complete the course.. I never know that she is so determined to study medicine.. she failed to enter medicine after 'A' Levels.. then she wants to try it again.. really impressed by her determination.. but it have to take so long.. by that time she will be near 30.. all her youthful years will be spent on studying liao.. I cannot be like that.. I have no interest in studying liao.. now I am just determined to complete the rest of what I have left.. I cannot bear any longer.. there will be so much waiting for me in the society for me to explore.. but I starting to have the fear of looking for job lor.. I find that I don't have anything that I am really good in.. something that I really can perform very well.. I seem to not have an identity.. I feel lost..

I am wondering why some people just have such a strong interest in something.. like my friend who really interested in life sci researching and lab work.. it's seems that my interest always changing.. I cannot find something that I can stay long with.. I will get bored so easily.. I am always fascinated by new stuff.. and this fascination never lasts long so I never have any skill and ability that I can be proud of.. I will lose touch of it soon after..

and I am wondering why some people like studying so much.. I used to like it.. now I don't liao.. why? is it so that they can enter the society later.. they don't like to face people.. all the politics and stuff.. studying will be the safer route to take.. isn't it escaping from reality? many people says studying life is better than working life.. working people just miss their student years lor.. is it really true.. I think I will know it only when I start working permanently bah.. and these long-years-studying ppl just have the ability and money to continue to study and maybe they just don't have the burden to feed their family.. they can continue to study with a peaceful mind.. I then don't have this privilege lor..
