What Chanel captures here isn't mere optimism, but a particular kind of ignorance that's actually productive—the difference between *knowing* failure is possible (which paralyzes most of us) and *knowing* it's inevitable (which somehow frees the audacious). She's suggesting that the successful person doesn't possess greater courage or willpower, but rather a blindness to probability that prevents the endless internal debate: *Should I try this?* A young entrepreneur who launches a restaurant without fully grasping that most fail within five years might succeed precisely because she never spent months weighing odds instead of perfecting her menu.
