One day a professor entered the classroom and told the students about a surprising test． He gave the test papers to all the students and said： "Begin"． The students were confused to see that there was not a question but just a black dot（点） in the center of the page． The professor noticed the students' face expression and told them， "I want you to write about what you see there．"

The students were still confused but got started with the test． At the end of the class， the professor took all the answer sheets and started reading each answer from each sheet in front of the students． All of them described about the black dot and tried to explain its position etc.. After the professor finished reading， the whole class was silent．

Professor began to explain， "Don't worry． I am not going to give you grades for this but I just want you to think about something． Here everyone focused on the black dot and wrote about it but no one wrote about the white paper． The same is with our life． The white paper represents our whole life and the black dot represents problems in our life． "

"Our lives are a gift to us by God， with love and care， and we always have reasons to celebrate ﹣ our friends around us， the job that provides us our livelihood， the miracles we see every day．"

"Still we just focused on day to day problems like health issues， lack of money， problems in relationships ect．， but we never see that these problems are very small compared with everything we have in our life．"
