When my son was in high school and doing the super judgey thing on a daily basis, I would get on his case about it. Constantly reminding him that he's not perfect and he shouldn't expect others to be. That he would be deeply offended if others judged his choices as harshly as he was judging others'. I don't know if it made too much of an impression on him at the time, but it changed me, because I started being really conscious of my own judgments. I would catch myself having those snarky, dismissive thoughts, and I came up with a mantra that actually changed my judgey tendencies after a while. "I'm no better." Whatever I was feeling superior about, someone behind me could very well be feeling superior to me. It was a quick and easy way to remind myself to treat others with love, even if they are blocking the supermarket aisle with their cart AND wearing leopard print! I was surprised by how easy it became to back away from those thoughts once I identified them. I still have them, of course, because judging others is a very human hobby and we can't help ourselves. I just quickly remind myself that I'm no better than anyone else and if they deserve to be judged, then so do I.

It works in almost all circumstances, except when I'm stuck behind someone driving too slowly. Then I lose my mind and unleash a flood of invective. Slow drivers are my line in the sand. No mantra works.
