This message teaches us to persevere, because failure is a part of life. With everything we do successfully or the things we fail we will learn a new thing, important things in life.For example in this image the youngster is standing next to his skate board so we can assume that he wants to break into this field, so by dint of work, of training he will succeed. This is what this poster wants to prove to us.
