Do you try to convince others to go vegetarian?

When I first cut down on meat and then stopped eating it entirely it was for environmental reasons. I was also thinking that me going vegetarian could inspire friends to become vegetarian. I find it funny how often the “why vegetarianism” topic comes up, and I’m happy to talk about it, I’m quite read up on the environmental impact of diets and let people know how that motivated me, then typically I just address questions they have or discuss with them if they claim I’m wrong. But it doesn’t seem to convince anyone to actually cut down on meat. One theory I have is that I, as a 40 year old, probably mostly talk to people over 30 that are already quite set in their way of life. Did you ever have any success in converting anyone to vegetarianism?
