I recently found myself being jealous of my cousin.. I was jealous of their situation and angry with myself. Not them. But I know nothing of how long they’ll be semi-retired. I know nothing of their expected lifestyle. I don’t know if they’ve inherited money. I don’t know anything. .......... Joseph Epstein put it perfectly, "Of the 7 deadly sins, only envy is no fun at all". .......... Being jealous of one activity should not extrapolate to a whole person. Sure she may wish she could travel like I do, but, does she really want to be me? She has no reason to be jealous of all of me, and nor should I of her. And we are the closest of relatives. We really understand each other. We are super close. So how misguided would be my jealousy of a mere acquaintance or a stranger? I need to keep training my mind to recognise these emotions. Then I can deal with them. Awareness is everything.
