For those of you who saw "The Matrix":
Neo was the One.
If Neo had known he was the One, he would not have tried to rescue Morpheus.
If he had not tried to rescue Morpheus, he would not have invaded the military stronghold, would not have dismissed bullets, would not have fought Smith, and would not have been shot. These events caused him to emerge as the One.
So... Neo was the One because he believed he was not the One.
It messes with your head.
