One day a professor entered in classroom and told students about surprise test. After hearing that all students were seated and waited for test to begin. Now, professor gave test paper to all students with text facing down at desk. Once he was done with handing out test to all students, he asked them to turn test page and begin. Student's were confused to see that there was not question but just a black dot in center of page. Professor noticed student's face expression and told them, "I want you to write about what you see there.."Students were still confused but got started with test. At the end of class, professor took all answer sheets and started reading each answer from each sheet in front of all students. All of them described about black dot and tried to explain its position etc.. After professor finish reading and whole class was silent. Now, professor begin to explain, "Don't worry, I am not going to give you grade for this but I just want you to think about something. here everyone focused on black dot wrote about it but no one wrote about the white paper, same is with our lives. we have a white paper to observe yet we just focus on dark spot here white paper represents our whole life and black spot represents problems in our life. as today all wrote about just black spot and no one noticed the whole white sheet same is with our lives.our life is a gift given to us by god, with love and care, and we always have reasons to celebrate - nature renewing itself everyday, our friends around us, the job that provides our livelihood, the miracles we see everyday..still we just focus on day to day problem like health issues, lack of money, problems in relationships etc. but we never see that these problems are very small compared to everything we have in our lives." 
We should try to take eyes off from our problems and enjoy each one of your blessings, each moment that life gives you.. Be happy and live life positively. .
