!!! Trapped In Life !!!

It so happens to me that I have an important assignment at hand that needs to be done urgently, or an exam scheduled the next day, but I end up in a bad mood which arises out of nothing..or may be out of a very very small problem which itself is oblivious of its existence..Whenever I am confronted with such a situation, the result is I end up doing nothing the whole day and so suffering negatively when the results are out.Why it happens so?Why are we carried away by such paltry things?The reason may be is that people like me lack determination.Or may be they are emotionally weak. I would never like to call myself any of these..But the reality is something or the other needs to be changed. I am always willing to change myself, but then also I lack the determination to do it effectively. Today I thought of starting my day with a good studying schedule.But somewhere in the corner of my mind had a feeling of selfevaluation..So althrough the time when i was trying to study,I had a feeling leaving it and doing the latter job, though i expected myself commiting to my studies.It isn't so that i ve not realized my duties as a student or i have misplaced priorities,But I get myself carried off very easily and reach a destination where every part of myself refuses to do anything..showing resistance to each n every thing... Hoping that soon i ll find effective means and measures to change myself and direct my efforts nicely..
