This is a slightly absurd complaint, but I find unspecific compliments annoying. I would prefer specific criticisms to a generic compliment nine times out of ten.
Because if I mess something up, it’s helpful if someone says, “Woah, that’s not right. Try this way.” I know what I need to fix to get better.
If I’m doing things generally and someone just says, “Great job!” then I don’t know whether I’m actually doing things 100% correct or even what my specific strength is. Whereas if they instead say, “The way you did that specific task was excellent!” or “I love your attention to detail/specificity on this thing” (pretend these are actually specific), then that actually gives me information and makes me proud of what I did.
But “Good job today!” as I’m walking out the door is just like “Thanks! I did 5 million things today… and definitely not all correctly, so I have no idea what it is I’m actually doing right….”
