A caricature,is the American University of the ads,the screen has four lanterns,arranged from top to bottom,and behind each light passage:
The brightest light the first:I have an idea,I would like to do.
The second lamp slightly dark:you can do?Give it a try.
The third lamp lit:are not in favor of the people around me to do,it is difficult to you!
The fourth most dark light:let us forget it.
In fact,everyone has these four lights,it tells us that regardless of one's life or brilliant mediocrity,success or failure lies in the choice of everyone.
