The first day when we go to school, most of us would be asked to set our life purpose by our teacher. Some will consider it carefully, but some do not take it serious. They may think there is no use to set life purpose, because they it is too long for them and the future is unpredicted. But, in my opinion, setting life purpose is very important and necessary. Although we may not get to the destination we want at last, we would not go off too far. If we have life purpose, we are not easily lost. Life purpose just like the lighthouse in the ocean guides us.
我们第一天去学校的时候，大部分人都会被老师叫设定人生目标。有些人会认真思考，但有些却不以为然。他们可能会觉得设定人生目标是没有用的，因为他们会觉得人生目标太长了，而且未来是不可预测的。但是，在我看来，设定人生目标是非常重要、有必要的。虽然最后我们可能走不到所希望的目的地，但是我们不会偏离得太远。如果我们有了人生目标，我们就不会那么容易迷失。人生目标就像是大海中的灯塔，指引着我们。
