The importance of attitude on life circumstances cannot be emphasized enough. Here's this interesting perspective to the well known David vs Goliath episode, which i came across while reading a book.

We all know the story of David and Goliath. There was a giant who was bullying and harassing the children in the village. One day, a 17-year-old shepherd boy came to visit his brothers and asked, "Why don't you stand up and fight the giant?"

The brothers were terrified and they replied, "Don't you see he is too big to hit?" But David said,

"No, he is not too big to hit, he is too big to miss."

The rest is history. We all know what happened. David killed the giant with a sling. Same giant, different perception.
