Goliath was a giant of a man. he struck fear in everyone's heart. one day a seventeen years old shepherd boy came to visit his brothers and asked, "why don't you fight the giant?" The brother were terrified of Goliath and replied, "Don't you see he too big to hit? but David said," No, he is too big to hit, he is too big to miss." we all know what happened. David killed the Giant with the slingshot. Same giant, different perception. Our attitude determines how we look at a setback. To a positive thinker, a setback can be a stepping-stone to success. to a negative thinker, it can be a stumbling block. Great thinkers and philosophers feel and believe that every problems comes with an equal or greater opportunity for success.
