caught up in the rush of life, we have forgotten how to live, how to find simple things charming(迷人的). taking a walk at night under the stars provides something that business deals cannot provides; enjoying warm sunlight, birds' songs and flowers’ fragrance(芬芳) is not for poets only, but for everyone. meditation(沉思), too, is a great need. meditation brings understanding of life's relationships, purposes(目标)，objectives(目的),and rewards, sharp focus. it is an aid for tense nerves.the only way to cope with tension is to learn how to manage one’s body and one’s mind. resting includes time in bed as well as short periods of relaxation. one may relax when walking on the street, by flexing(收缩) his muscles and erting(快乐的) his mind to things around him. moreover, enough time should be taken for a leisurely(从容不迫地) lunch. the most inefficient(无效率的) way of handing tiredness and pressure is to take stimulant(兴奋剂) or drugs.

　　everyone has only 24 hours a day, and a limited number of years to live. so we need to admit limitations of physical and mental strength, and to keep within those limits.
