It's hard to believe that one day your dream will be true.
The little boy from the picture made a plane from the paper and he is looking at him with a hope. He is saying: Please...fly...please.
It's not necessary that he will become a pilot.
The image makes us feel a hope that we are having when we are kids. It reminds us about our striving for happiness. When we are young we thing that everything is possible. Our parents used to encourage us.
What happens right after we become older, at least 20 and something. We have gave up already. But why? It's only a beginning...Beginning of life.
We lost our paper plane in silly prejudices.
