There was half a glass of water in the crystal glass, and someone asked, "Why is there only half a cup?" And some people say, "Great, there is already half a cup," and the optimistic person can struggle to find an oasis in the desert, but the pessimistic heart sighs sadly because of a cloud on the edge of the clear sky, happy or unhappy, not far away; Success or unsuccess, often in a thought, good morning!
晶莹的玻璃杯中有水半杯，有人问：“怎么只有半杯？”而有人却说：“太好了，已经有半杯，”乐观的人能于沙漠中奋力寻找绿洲，悲观的心却为晴空边上一丝阴云而悲伤感叹，快乐不快乐，相距不遥远；成功不成功，常在一念间，早安！
