He will always be attracted to the woman who reflects his deepest vision of himself, the woman whose surrender permits him to experience a sense of self-esteem. The man who is proudly certain of his own value, will want the highest type of woman he can find, the woman he admires, the strongest, the hardest to conquer--because only the possession of a heroine will give him the sense of an achievement.” 

― Ayn Rand, Atlas Shrugged
