People always say that life can't goes on well all the time, because we will meet all kinds of difficulties. When we are students, we want to get improved and do well in the exams. When we graduate and find a job, we need to finish the task that boss has assigned. Even the time comes to retire, we still need to find something to do. Setback is part of life, and we should get used to it. When we face the difficult time, we should consider it as a test for us and when we get through it, we will gain valuable experience. The pleasure we get makes us proud.
