With time going by,I did nothing no matter what I like or dislike.NOw I really want to do something to make up for the days I waste in vain.Everytime when I fall asleep ,I will think what I have done today ,I really regret what I have done which make no sense. I make decision once and once to study hard.But everytime I defeat myself quickly.I am sorry to my mother ,my father and my sister.Thank you for all what you have done for me.
