When someone in a creative industry says “This was a big project, and I am thrilled to get to contribute to it. The work done by persons X, Y, and Z was both critical and amazingly good” I am both impressed that the speaker is connected enough to know who did good work, and pleased they were able to work with others to make the best possible product.”
When a creative says “I did all this, and all credit goes to me” I am immediately suspicious. Sure, in some cases it’s true. And when I know the person or their project well enough to know it’s true, I am impressed. But 9 times out of 10 when I look into such claims, there are numerous important people the speaker is covering in shadow, and that’s not cool.
