A bit upset

I feel a bit upset recently...
i realise that i did not noe many things....
i'm so weak....
how do i catch up with them?
work hard? i dunoe...
many things to learn...
i determined wan to learn many things in my sem break...
i wan to use my time wisely...
if i din't work hard...i sure will b very behind...
Gambateh ! Wai Ying!...
