1) >>>雖然說,我只是一個學生而已.
我還是必須打工(一星期上20~25小時.)<<<
Me and my American buddies worked long hours in college years too. It is not only you need to do it, so....I regularly slept only 4 - 5 hours a day.
2) >>>很難得碰到互相欣賞喜歡的男生...<<<
Dating is very common, I mean like go to see movies, ice cream house... My bud told me not to put it too seriously, then you gonna have fun. Go to disco in town once a while, relax.
3)大學生不是該Have Fun & Enjoy Life嗎?
It depends on how you look at it.
From your information, I give you 2 words 'GET FOCUS' on what you have been doing, and life will be better. Look at the mirror and tell yourself you wanna be a winner rather than a loser EVERYDAY
