Sleep

How much sleep do we actually need? "7 hours of uninterrupted rest"? Why do we feel sleepy at times when we're not supposed to, and yet have that energy to jolt you up once that a day's lecture/work is over? I used to wonder why my classmates can easily escape their way to dreamland faraway from Trigonometry or Diary of Anne Frank, when I still kept my eyes open and mind awake. Soon after, I hopped on the ride and faced the Z-monster (Level 50) at places like the cosy freezing LT 17b and Sierra Company Training Shed.

Let's not push the blame to the dry subjects or the monotonous speaker or any other reasons you can think of other than ourselves. (As usual, the blame-the-whole-world-but-yourself mentality).
We're just lacking in that discipline to learn and respect for the speaker.

Pardon me, I'm "army-fied".
