You should share your open-mindedness and new point of view with someone who thinks the way you thought in the past. Spread the enlightenment around. At first they might think you are being a know-it-all and talking down to them, but keep at it. Soon enough they’ll see that you have their best interests at heart. They are smart enough to get it eventually, so don’t give up hope that they will come around to your way of thinking. Just keep talking and making suggestions.
