The modern pace of life is just too fast. Everyday as you open your eyes in the morning, you have to move fast or you won't get things done on time. You have no time to enjoy breakfast; you have to run in order to catch a bus; you have to shout and yell to get other people moved; you have to be nervous all day long. Since what time we human become such miserable creatures? It's because of money, which can buy almost every thing in the world.With such a powerful stimulus, we people act like drug addicts and become oblivious to the true meaning of life.
