I wish people would talk about their work more. There's so much to learn about how different industries function that's invisible to outsiders.
I don't want to hear about office politics, but I want to hear about your suppliers and customers, how do you decide what to sell, what to buy vs build, what weird regulations or norms exist in your industry, who are the experts in your industry and how did they become experts.
The productive part of our days are at least as interesting as the leisure parts.
