Who becomes the world's best with a broken shoulder?

According to Rune Glifberg, significant achievements will always involve fear. So you have to find a way to overcome that fear and believe that what you're embarking on will be a success. Glifberg has a set of tools to trick his brain so that fear doesn't take over: he visualizes his run inside his head, he takes the leap from the shallow end many, many times before jumping in the deep, he tells himself that failure is also a result he can learn from... The brain loosens up, and some of the pressure dissipates, allowing him the freedom to perform at his best.
