Did you find anything interesting?
Well, it obviously just looks like a color blindness test, but if you observe the picture carefully, you will find that they are just simply colourful dots, arranging randomly. ( Please don't doubt this because I actually checked about it online and this poster is just a fooling trick! )
However, when I first saw this picture, I checked again and again as I didn't spot any numbers in the colourful circle. Then I started to worry if I had colour blindness. But at the end, I found out that this poster was actually a joke.
Why would I always stick to the common sense and never raise up new ideas spontaneously? The only thing that doesn't change is change itself. What kind of person will I become if I do not learn to doubt on old ideas and investigate on my own? A person like that can never succeed because he/she is only able to follow what they are told.
I must start training myself to think, positively. Yeah, starting today!
