It is only a failure if the person gives up, and drops dead!
One of my favorite verses from the Bible is "Rejoice not against me,O mine enemy when I fall I shall arise!" Micah 7:8
For those with a dream and desire it is only a set back ,an opportunity for growth, a step before victory, but unfortunatly many people give up to easy and fear keeps them in bondage for life. The children of Israel saw themselves as grasshopers therefore they spend forty years with Moses and died in the wilderness! It is a matter of perception!
