i feel that i am in another world during classes

paying attention and staying force during class are needs during classes
unfortunately, when lecture was teaching in front, i was staring either at her or the paper
the most important was my mind was tuned to blank state at that moment but not absorbing the knowledge that they are trying to give out.
eventually it's because it's career exploration week or maybe i'm just lazy
argh!! laziness is attacking me again

sigh,
