How can I be successful as a student this semester？

Success, what an inviting word it is, it’s the same to me. Though I haven’t been successful, but I want to depend on time-balanced, co-operation and good attitude to contribute to making an achievement as a student this semester.
Time-balanced ranks the first place, I think, because it's the foundation of anything else. It includes arranging time between study and entertainment, work and sleep, compulsory assignments and freedom. I fell asleep deep late during the last month, so that I didn’t be charged fully, I probably performed less efficiently. Sometimes I couldn't maintain the balance between compulsory assignments and freedom, I felt like a person who misunderstood the meaning of life. I usually think I can control my time well. Not exactly, in fact. Developing a good schedule is about to help me make a different, I believe.
co-operation is the second place, that's because however erudite I am(in fact, I really know a little things all the time), my knowledge is limited as well, so the best way to cover the shortage is keeping co-operation with the others. Once, Zhang Liang and I were responsible for the games of Jungle Travel, but I couldn’t come up with some good ideas by myself. At last, I ask Zhang Liang for help, and his ideas were also not enough. To our surprise, we created many ideas that we didn’t ever think of. Though the ideas weren’t put in practice, but that discussion makes know how important cooperation is. It reminds me of finding the solution to the difficult problems during the secondary school. I think, it will help me to continue the success at school as well.
Attitude taking the third place doesn't mean it's least important among these things, that's because my attitude is developed with the advance of time-balanced and cooperation. For example, I ever thought playing computer games was more exciting than anything else, so I gave up the sleep time and the activities with friends; it's obvious that I feel tired during the working hours and lost some good friends. Because of a negative attitude, balance is broken and co-operation is disconnected, as a result the success become more and more far away. However, I am doing my best to change my wrong attitude so that I’ll become successful.
As the saying goes“All roads lead to Rome” I’m sure relying on the three keys, I am about to be something as a student this semester and just like you. Come on! Thank you and that’s all.
