I think the most serious effect is on my studies. On weekdays, after class, I go home and play computer games for an hour and then do homework for less than an hour. Furthermore, in weekend, I usually stay up until midnight. and then I watch movie for killing time. One day went, but I have not finished my homework. Because of laziness, I can’t finish homework on time and that is really harmful to my study. What’s more, in my speaking and listening class. Every time, we do some group assignment, I am not the person who can be leader, because in group cooperation,the leader has to pay more time and energy to help the group to do assignments. However, because of laziness, I have little energy to do the assignment. In fact, to be a leader in a group is good way to help someone become more responsible.
