The thin-skinnedness has always kind of shocked me, as I assumed that people who both desired and held a relatively public role were sort of used to and could handle criticism. But it isn't actually that way. It's very strange.
There are certain kinds of criticism that still annoy me, mostly when people who are nominally on my team assume all kinds of absurd bad faith motives on my part, but otherwise you learn pretty quickly to sift through stupid and valid criticism. And, frankly, I'd find this boring without it.
