How would you feel being judged as several levels below me?
In 2013 or so, after going to a congress I booked another 5 days in the cheapest Hostel I could find (in New Orleans) and slept in the large sleeping hall in a bunk bed. One night cost me as much as the wifi in my previous hotel. And I met a teacher doing charity work on the Katrina disaster houses that were still dealing with fungi. He took me around the sites, to camp hope, I ate with all the volunteers. Many Christians and Mormons were there, this was new to me and I don't agree with religious people on many things but it was a wonderful experience. One I would have certainly missed with your attitude. On another night I met an artist living in a van that ran on waste cooking oil she filtered through old jeans. She was very conscientious about our planet and reflected that in her art. She thought me that art, like words and code are a means of communication but more on the emotional level. I never looked at it like that. I didn't see a single PhD that week and I liked it at least as much as the week before, talking about single molecule biophysics.
One of the most important lessons (imho) I teach my kids is to withhold judgement. Do not put absolute values on anything or anyone in a short amount of time. You will do yourself and other a disservice. Someone cutting you of in traffic may have a sick kid at home and in a hurry/distracted, someone being rude may have just been fired and about to burst in tears, etc.
