Don't demonstrate frivolous jealousy at your friends' success. If an acquaintance is wearing a new tie or a new blouse that you yourself would like, don't capriciously point out its shortcomings to him or her. "Yes, it's nice, but it has a stain on it." That will only serve to irritate him and won't help either his or your practice.
