I've always had issues with jealousy. I got jealous when my younger sister got married because she is several years younger than me. Somehow, I thought I was suppposed to be the first one. I'm jealous when people get promotions, especially when they already had a job to begin with that I would have liked to have. I've never been promoted in my life and there are people younger than me in their 20's getting promotions. I'm jealous when others get to travel the world and I'm lucky to be able to afford a trip into the next state. I'm jealous of other peoples' parents. Like they understood their children more and weren't so overprotective of them and had more faith in their abilities. I'm jealous of people who are seemingly more well-rounded than I am. I'm good at academic type stuff but not a whole lot else. Other people are just as good at academic type stuff in addition to sports, music, and art. It hardly seems fair. I know there's no sense of entitlement and life isn't always fair but I've always had this strong need for a sense of equalness.
What usually pulls me out of this funk is thinking about people who obviously have it way worse than me. For example, someone in a ravished third-world country who has never had access to sanitary conditions, where disease and war are rampant, as well as illiteracy. Then I start feeling guilty for having it as good as I do.
