 You know, like, I don't know if this is true, but they said Einstein never memorized his phone number because it would have taken up too much space in his mind. And he didn't want to waste that space. That's very true. If you've got to have your calendar app open in your head constantly, which we all mildly do, you can't just go out today going, what's next now? What's next? What's next now? I mean, most of us have to have a general understanding about what's coming. But yeah, it reduces pressure if you write it down. But you now have to check it.
