Subject: Munger on Envy
According to Munger, envy is particularly detrimental. He highlighted it as one of the most foolish sins, with no redeeming qualities: "The idea of caring that someone is making money faster than you are is one of the deadly sins. Envy is a really stupid sin because it's the only one you could never possibly have any fun at. There's a lot of pain and no fun. Why would you want to get on that trolley?"

I think that applies not only to money and possessions but also to people who get more recognition and recs than you do.
