Without strong focus there is no way to achieve excellence. Really. It's just that simple.
There are two regions in the brain responsible for our ability to maintain focus. One brain region is associated with concentration. We all know about concentration. No biggie right? Most traditional meditation methods work to improve our capacity to hold our mind on one point or object. Another region supports the ability to ignore the irrelevant. These regions are similar in location and composition, but support wholly different aspects of focus. Ignoring usually plays a lessor, or complimentary, role to the primary directive to concentrate.
