I agree...
Generally speaking males have stated that they FELT destined for greatness. When they do settle down to a life of the mundane, they feel they have failed, somehow...thus buying into the fallacy.
Most people are not destined for a life less ordinary.
The invincibility aspect is a fallacy males instinctively adhere to and it is a severe disappointment/sense of failure when they discover otherwise.(and they will)
The Cinderella fantasy that females buy into, becomes a crushing blow when we realize we have set ourselves up for disillusionment. Our significant others don't stand a chance to this malignant line of thinking.
We all seemingly fall victim to this ideology on some level.
