I guess it makes sense that you've got impostor syndrome when so much of what you do is made of words and thoughts; you can't open a vault somewhere and see poems and ideas heaped up around you, stacks of conversations and little chests full of conversation. But they did happen, and they matter; from what I've seen of you, you've consistently been a deep thinker, keen observer, and devoted worker of words. That's real work, and it counts, and it makes you a rich asset anywhere you go.
