Brightness
How much light you bring to what you're looking at. Controls whether you see the hopeful side or the dark side of a situation.
Bridget Ball and the Reframe of Poison
Brightness perfectly captures how Bridget Ball consciously chose to see the hopeful side of chemotherapy instead of focusing on the suffering. She literally turned up the light on what she was looking at - seeing lifesaving medicine instead of poison, seeing rescue instead of harm. This wasn't about ignoring reality but about choosing which aspect of the reality to illuminate.
