do we live to study?

Assalamualaikum dear frens,
i'd like to share to you all bout my experience in studies. Honestly, i luv studying when i was 15, that is when i was sitting for PMR. I became addicted to study and love to learn each day and enhance my memories on facts especially history. I even study on Friday evening. Can you belive it? I can't either. To become a good student takes such a long time but when you just be patient and think that when there is a will and there is a way, you'd make it through the rain. I was so happy on the day i got my result till i cried and my mum cried too.
But when i was having my SPM year, i became different. I hardly study hard. I get to learn that my weakness is actually my self compleasant. Since that i already got straight A's in PMR, i thought that i dun have to work hard for my SPM. And I forgot the fact that SPM reflects my future life. My schedule became so disorganise till I became a failure. I failed in lots of many subjects including addmath.. I hate addmath soooo much. But in the end I manage to get A2 in it, haha. Dun believe it either. That is called rezeki.
Now, studying is a must since that i'm in this course where no mistake is affordable. Cuz once it happens, people die. So i'd have to study real hard and struggle to score. So it got me thinking that i should always study and nothing more. Life gets so much boring and stressful since that there is no such thing as Midvalley here in Jakarta. Hate the fact so much but....I have to face it since this is the path that i've chosen. So far i've faced failure and about to repeat the paper that i've failed in. Why do we study so hard to pass? What exactly is our purpose in studying? Is it to have high marks? To show off to your frens? So that your mum wouldn't be dissapointed in you?
Believe me that if you study for those reasons, you might break real down if you happen to fail. Because you only think of your target and the marks or pointer that you've aimed for. But try to study because of Allah SWT, wanting to explore Allah's knowledge. If you happen to fail, you won't feel down that much because you know that Allah will only look at your hardwork and effort that you contributed in, not the result that you get. This is cuz every single thing has been written in LAUH MAHFUDZ. And it cannot be erased or changed until the end of the day someday. Your failure is written there.. so if you are destined to fail, you will fail . But what you could mend is your hardwork that will be judged by Allah SWT.
So what i really take from this, is that sajikan Allah SWT dengan usaha kita yang bersungguh2 . Dengan harapan Allah melihat usaha tersebut dan memberikan credit yang baik kepada kita sungguhpun by the end of the day we are destined to fail..Insyallah.
