Do you lead a well rounded life? Are you leading an unhealthy lifestyle because of poker? If so, your friends might be right. Poker is fun and even if it is beatable, I don't think it should be overdone. Maybe your friends have sensed that you have an impulsive personality or that your life isn't well rounded. At the very least, I would quit talking about poker around people who aren't interested in talking about it. If they aren't interested, just leave it alone.
