Narcissism razor: If you're worried about people's opinions, remember they are too busy worrying about other people's opinions of them. 99% of the time, you're an extra in someone else's movie.

When we feel uncertain, when randomness intrudes upon our lives, we respond by reintroducing order in some other way. Superstitions and conspiracy theories speak to this need. It is not easy to accept that important events are shaped by random forces.

Sofa friends versus treadmill friends. And there's certain friends that I hang around with, afterwards, I need to lie on a sofa because they kind of drain you of that energy.

If you were to go back to 1850 and try and explain the concept of Wi-Fi... it would not be seen as fathomable. But the idea exists; you just need a combination of ideas, which we spoke about earlier, and then high-agency individuals, and humanity working together and compounding.
