You are much less complex than you think you are. Everything else is much more.
We view things we don’t know about as monoliths, simple entities with simple rules. The reality couldn’t be further from the truth. At the same time, we think of ourselves as these deep beings with rich tapestries of motivations, but we’re mostly just status-seeking machines who eat sometimes.
Anyway, it’s a good thing to keep in mind. Don’t make too many assumptions about the world until you go and look, and remember to be a bit more humble about yourself.
