If you are a chronically jealous person, then the chances are that you feel that you are not a person who is worthy of admiration because you are not exciting, interesting, or dynamic. It's time to work on making yourself into a person who has no reason to be jealous because you're so happy with who you are.  Here's what to do:  Develop your self-confidence.

No two people are alike, and you'll only feel worse if you're trying to emulate someone else. Though different people should inspire us in different ways, don't forget that you are a unique individual and never compare yourself to anyone else. You may be jealous of others because you can't stand the things you do on a daily basis. To avoid this, you should be...
