I think envy is instinctual in gregarious animals. It's a mechanism for social balancing. You can't stop the feeling except to be at the top of the social hierarchy. You can control your behavior when you feel it though.
You can practice by surrounding yourself with people better than you. Play games with people better than you. Find mentors.
Grow as a person so you love yourself rather than envy others. Recognize that almost everyone has something you don't. Better than you at something.
Reflect on the great things about yourself. Remember who you are. Where you started.
Be good. Be true to yourself. Develop your moral code. Treat all with respect and love. Including you with all your imperfections.
