 I'd like to ask you, think about your brain for a second. Why would I ask you to hand write down information? Any ideas? Any thoughts there? I'm going to give you a really big hint. All learning depends on great systems that work well, especially cognitively your memory and your attention. And writing down something is going to facilitate that a bit, right? Do you know what some of the oldest things that were ever written down, do you know what they were? They were debts because you lent me three, three euros and I wrote it down, but you come back and you say, oh, here's the euro I borrowed and I said, no, no, no. It was two. It was three. And he said, no, the only way we can have a common and shared understanding is if we document it. So do write things down, okay? Write them down for your own good, but for everybody else's good.
