Flipped open my nuclear physic tutorial, read the questions, *I think I don't know how to do*, put it aside.

Then I flipped open my nitrogen compound notes, try to study a bit, *it just can't get into my brain*, put it aside.

Flipped open my econ workbook, stared at the case study for a while, *sian, don't feel like writing*, put it aside.

Flipped open my vector notes and try to study, *damn, I feel like using the computer*, put it aside and start using the computer.

Haiz... How? Totally no mood to study. :(
