have you ever known someone who seemed genuinely determined to take you down? i'm talking more of a personal than professional thing, though accounts of the latter would be interesting too. i never really experienced what it was like to have an 'enemy/rival' until last year; it was a fascinating experience to say the least, and i'm glad to have gone through it. i'll describe my situation later, but first i'm curious whether it's typical for people to make enemies or rivals. sometimes they're genuinely better than you, sometimes they're not. sometimes the circumstances are in your favor, other times not. what caused the antagonism? how did you adjust your behavior? what was the outcome?
