Life is always Rough, I Need to be Tough

At the beginning of new semester, students usually excite to study. They excite to get great scores on the tests, or they excite to finish all of the homework assignments, etc, and when they got good grades and have done all of the homework assignments, they feel so wonderful. Sometimes, they couldn't finish all of the assignments, and then got bad grades on tests, the feeling of fear, sadness and disappointment suddenly came to them. I was one of them. However, I encourage myself do not give up, but keep trying to do the best I can do. Life is always rough, so I need to be tough.
