One day a teacher went to her classroom and told her students that they would have a test. The students took their seats and waited for the test to begin. The teacher put a test paper on each student's desk and she then asked them to turn the paper over and begin.
The students were surprised to see no questions, but just a single dot(圆点) in the center of the page. The teacher said," I just want you to write down what you see on this paper".
At the end of class, she took their tests and started reading their answers. Minutes later, the teacher started to explain. "You tried your best to finish the test. All of you wrote something about the dot. Some thought it was a black one. Some thought it was brown. A few thought it was really small. While others believed it was big enough. But on one wrote about the white area around the dot. "
"Imagine that this paper is your life. The white area is all of your life experiences—the black dot just stands for the bad things you've gone through. Life provides us with many things —loved ones, happy moments, and even some other good things. However, we sometimes only pay attention to the bad things. Our problems and difficulties can beat us"
"From now on, I want you to think about the big picture more often. Don't just focus on the black dots in your life. Remind yourself how lucky you are sometimes"
