" If you keep experiencing the same things, your mind keeps its same patterns. Same inputs, same responses. Your brain, which was once curious and growing, gets fixed into
deep habits. Your values and opinions harden and resist change.

You really learn only when you’re surprised. If you’re not surprised, then everything is fitting into your existing thought patterns. So to get smarter, you need to get surprised, think in new ways, and deeply understand different perspectives.

With effort, you could do this from the comfort of home. But the most effective way to shake things up is to move across the world. Pick a place that’s most unlike what you
know, and go. This keeps you in a learning mindset. Previously mindless
habits, like buying groceries, now keep your mind open, alert, and noticing new things. New arrivals in a culture often notice what the locals don’t. (Fish don’t know they’re in water.) "
