I never think to look for the positive in a situation--how sad is that? I suspect there are many of us with this particular visual impairment. It's not that I look for the negative, but that I've got a sort of blind spot for the possibility of the silver lining. The stubbornness of the negative is mind-blowing and daunting--the kind of energy it takes to climb up and over it in order to see to the other side is obviously something one needs to condition for.
But now that it's been pointed out to me--this habit, this worldview that I never even realized I carried--I think the light might be shifting enough to see the panorama, the landscape of possibility, along with alternate routes over, around, and through.
