I was really struck by that idea you just mentioned of currencies, how all these social platforms have these different currencies. So money is one, but now we've got all these other currencies that we are shooting for. I found that part to be really interesting because I hadn't thought of it in quite that way. Dopamine is why we keep coming back for more, and the brain networks is what I would reiterate there. The thing to internalize is that the networks that support our craving more are anti-correlated with those that make us present in calm.
