All great advice, thanks for these reminders.

If you don't know something say so rather than pretending you do.

Reminds me of a funny story that happened to me. I was in the car with someone I had just met. I got the feeling he was trying to impress me and he used a big new word I had never heard before. I don't remember the word now, but it was something like "gentrification" or similar.

I thought it was an opportunity to be humble and let him show how smart he was. So I said I'd never heard that word and didn't know what it means, and asked him to explain it. He was dumbfounded, stuttered a bit, and said he didn't know what it meant either. 😂

A long way of saying, I've been surprised at how often other people are in the same situation and also don't know something. A lot of people are pretending they know things and afraid to admit they don't. It's a type of freedom to be unafraid to admit you don't know something.
