my late period of STUDY?

once upon a time, my study began .

it seems i have formed my habit of taking study for my daily life over the past 16 years.

well. time flies till today .i still can't break through all the restraint i got..........

Therefore , my late period of being a typical student has begun.

sigh.obviously i have to take it and to be a *GUAI* student in despite of refusing .

so what's going on?that will be a really desired answer i am always looking forward to !!
