A story for to the Value more the things of the Life.

One day a teacher entered in his told the class that there is going to be a test.

Today we going to do a test.

Every All the students were nervous, because it wasn't unplanned any exam. The teacher gave them a white sheet of paper to each student. He asked them that they would turn over the paper to  look in at the other side of the sheet.

In the other side only there was a black spot in the middle on the sheet. Except for a small black dot in the middle, the entire sheet was blank.

"Now I want that you to write something at what you see"about it, said the teacher.

The young students were confused, but after a while, they started their writing. they thought and wrote about it.

All the students wrote about the black spot of in many different ways.

The teacher said them, told them that this isn't an exam, only is for but a lesson in your life. All Without exception, you all wrote have written about the black spot, but and nothing about the white   sheet space. In the Life is same, we have a whole the entire white sheet. for to see and to use, but However, we only we focus in on the tiny black spot. The Life is a precious gift. of the nature, We have our families and our friends to fill our lives with love and affection, etc..., We have a lot of many reasons to celebrate. however Why do we insist to looking at the tiny black spot, when it is tiny respect the white sheet ? 

Stop focusing on Out your attention to the black spot and, be happy!

Nice teaching.  I have a question?  If the colors were reversed, that is a tiny white spot on an expanse of black? Then what?  Would the morale of the story be the same?  Colors play an important cultural psychology :)

Firstly thank you for your corrections.

About your interesting question:
If we would invert the colors it may happen several things.

I explain it:
The students only can have described the black color, independently of the size, because it represents the dark, the unknown, therefore induces fear and our survival instinct try to protect us and forces us to give more attention to black color.
Instead the white color represents light, clarity, purity, we feel comfortable and don't need to be alert.So according to this argument, if we invert the colors, in this story the result will exchange.

But also it can argue it differently.
By nature, we are always alert and pay more attention to the strange, to what is different. In this case, against the previous version, independenly of the color we use, always the small spot will be the strange in the sheet of the paper comparing it with the other color that it will be the dominant.
In this other case there would be no change in the story if we reverse the colors

But independenly of these arguments or others, the important in this story is that there are small negatives things in our lives that they are able to grab most of our attention, so disproportionate, and depend of our capacity to invalidate them.

Finally, curiously my favorite color is black, my car is black, a lot of my clothes are black, etc.. I love black.
