" Good coaches have been doing this for ages. Now we know from brain science why. Our neural wiring and circuitry are built in the context of encouragement and positive emotions. Research on goal setting offers a number of important lessons when it comes to building Corner Four challenges. We know, for instance, that the goals we set for ourselves and others must be challenging enough to activate our energy and our brains, but they also must be realistic and achievable.
It’s also important that the difficulties of achieving these goals be spelled out and addressed. Blind positive thinking, the research shows us, does not work, because when obliviously positive thinkers encounter difficulties, they get discouraged and bottom out. Corner Four people not only help us believe that we can get there, but they also help us see that it is really, really going to be a lot of work, with lots of obstacles. They make the difficulty normal. They will be there to cheer us on, but they will also be there to talk us through difficult patches. "
