Tunnel Vision
Most vision casting is tunnel vision casting. Not because it doesn’t see clearly but because it doesn’t see widely.
Tunnel vision fixates on one thing (and that one thing is the most important thing that exists). Healthy vision looks ahead through a wide-angle lens, always waiting for surprising inputs and unexpected forces.
Tunnel vision wears blinders (and by definition cannot see them). Healthy vision includes peripheral vision, as it accounts for the future that never comes head on but always comes from the side, from a place we have no chance of predicting.
Tunnel vision sees what’s in focus (and insists that anything out of focus is a distraction). Healthy vision looks ahead and sees the dynamic interaction between what’s in focus and what’s out of focus as a place for creativity.
Tunnel vision is fixed and rigid (and criticizes malleability as weakness). Healthy vision is elastic and intentionally flexible, knowing that rigid boundaries can never stretch to include what only later we will see as valuable.
A vision that sees widely is not less descriptive or focused but it does welcome surprises as gifts to discern and challenges as opportunities for serendipity.
Cast your vision, but don’t ignore the periphery.
