Realize that there are no accidents. We are all on our own path in life and experience different things exactly as we're supposed to. Comparing yourself to someone else is senseless and based on fear and a sense of lack. We are each living on the same planet but not at all the same world. Trying to find happiness externally will always lead to sadness and depression. That person you judge to be superior to you has their own set of problems to deal with. Also, as the other commenter said, get off Fakebook. Other people's lives have nothing to do with you.
