Smiling is an attitude(态度)to life. In our life, there may be something unpleasant. For example, you fail in an examination; or another time, you are misunderstand by your friends. These unpleasant things may make you feel bad. Then what will you do? Why not learn to smile? Smiling to yourself can bring back you confidence. Sometimes, the greatest enemy is yourself. that’s to say. Sometimes, you are beaten by yourself. We should also learn to smile to others. It will help us to get closer to others. So smiling is the most widely understood language.
