Billy has been playing baseball for nine years. He especially likes batting, and he can hit a ball into the outfield very well. But his coach says that’s not good enough. ‘You can hit a ball far, but I want more. I want you to hit a target too, not just hit the ball anywhere,’ said his coach. The problem was that Billy often hit foul balls. His coach set up a target for Billy to hit. Billy complained that it was too easy, but hitting the target turned out to be more difficult than Billy thought. After that practice, Billy started to make a mental picture of the target. Soon, in his practices he was hitting the ball wherever he wanted. That’s why Billy likes his coach so much.
