I already know this.
I often look for this red flag.
Because I chose to be in the situation. I showed up for the workshop or talk or discussion.
Why, then, does it seem so easy to write something off as "known" and dropping my focus for the apparently-more-important task of checking my phone.
Firstly, it's totally inconsiderate to the person who is trying to teach me as well as the others in the room.
Secondly, what will it cost me to hear it again? Nothing. I just don't like the discomfort of being told something I think that I already know.
I've never felt like it's been a waste to lean in. If I did know it all, I can expand on my existing model by hearing someone else's vocabulary around it.
More often, though, I find that I find some fundamental gap in my understanding or someone raises a question that I would never come up with on my own.
The thing that's more interesting than the opportunity cost of "knowing" is the friction itself.
What is so wrong with hearing it again?
Why does some part of me throw up a wall?
I think we got trained be the gold stars we got in school for being able to jump ahead.
Time to trade them in for some patience, I think.
