IMPOSSIBLE?

I have the privilege of spending time everyday with my youngest grandchild.  I've watched this busy one year old as she is confronted with challenges and obstacles. I enjoy watching as this new little mind attempts to solve problems. She is so creative in her approaches and I began pondering this intriguing demonstration. It then occurred to me that she has yet to learn the concept of impossible. Because of this, her thinking is unlimited. Have we allowed the concept of impossible to limit our thinking, our problem solving? What would happen if we removed the concept  from our thinking?

Where would I possibly find enough leather with which to cover the surface of the earth? Yet wearing leather, just on the soles of my shoes is equivalent to covering the earth with it.
