This is the story of the three little pigs — from a mental performance perspective.
The three little pigs live with their mother, who, having spent years raising them, launches them from her home and into the world. So each pig needs to find a place to live. The first builds her house out of straw, the second builds his out of sticks, and the third builds hers out of bricks. The villain of the story, a wolf, comes along and blows down each of the first two houses, sending those pigs running to the protection of the third pig’s sturdily built home. The wolf discovers when he reaches this house that he can’t blow it down, so the pigs get to live another day in peace.
So, what does this story have to do with mental performance in baseball?
