Dead Ends and Framing
The frames our minds create define—and confine—what we perceive to be possible. Every problem, every dilemma, every dead end we find ourselves facing in life, only appears unsolvable inside a particular frame or point of view. Enlarge the box, or create another frame around the data, and problems vanish, while new opportunities appear.
