Growing up I absorbed the pernicious belief that one finds focus in the environment. Someone close to me passed along the idea that focus requires certain situations, for example, a quiet place without distractions. A foolish idea. A person with that belief will never find focus anywhere because they've misplaced the locus of control.
One finds focus within, or not at all. Sure, focusing in a dark cave might prove easier, but in order to grow we must not seek ease. We seek challenge. Our focus grows stronger through use in chaotic and difficult environments.
Do professional athletes compete in perfectly silent sound-proofed stadiums? No. They compete in colossally distracting stadiums filled to the brink with obnoxious crowds, blaring music, announcements, and other obstacles. How could they possibly do that unless they had highly developed focus? Athletes demonstrate that we can develop a honed strength of focus that serves in the most challenging situations.
