Everything has possibilities. A discarded piece of lumber can become a bicycle ramp. A stack of computer printouts can become a hundred paper dolls. Children are not burdened with a lot of pre-conceived notions. Their minds are very open.
Children are endlessly creative in ways that few adults can even hope to be.
It is a shame that this open-mindedness and creativity gradually fade away as children become adults. As we learn more about how the world works, things begin to lose their magic. As we become more logical and educated, we tend to look right past the beauty and wonder that surrounds us. A big part of maturity is discipline, which puts a damper on the impulsiveness of youth. Discipline is a very necessary thing.
