What do you complain the most?

I often complain about study and some people who I don't like.I complain about the final exams recently.So terrible,coz there are so many things to recite!Oh,my god.

I never complain about anything in life, so long as i am alive , i can't find anything to complain except thank God for his blessing. Compare to those who suffered from the destruction of war, tormented by the rule of oppressor, and the hungers, the poor and the sicks, I have nothing to complain.
