 Good morning, John. A couple hours after I went to bed, two nights ago, my house started to shake a bunch. Turns out it's because the earth under my house was shaking a bunch. To be clear, this was not a serious earthquake. I think the biggest casualty was this pasta sauce. But, to be additionally clear, it did not prevent Catherine and I from totally freaking out and running into the baby's room as fast as we could to stand there and watch him sleep as if nothing had happened at all and not do anything because it was over by the time we got there. It was a 5.8 on the Richter scale. And if you've been in a 5.8 before, you know that it's sort of like standing on a train that's moving, which is not nothing. Like, it's not what you expect the earth to do. And the Richter scale tells you pretty much what you want to know, which is how much the earth is moving. Maybe it doesn't actually tell us what we want to know. In 2010, if you remember, there was a magnitude 7 earthquake in Haiti. This is a much, much bigger earthquake, much more destructive, hundreds of thousands of people died. That year, there were 20 other earthquakes that were stronger than that earthquake in Haiti. And the combined death toll of all 20 of those more powerful earthquakes was less than a thousand people. The earthquake in Haiti was so destructive for two reasons. One, it was centered very near several different large population centers. And second, because Haiti is such a poor country, the buildings weren't well constructed and many of them collapsed. So that number, 7.0, it tells you something, real information, but it doesn't tell you everything. And this is related to a thing that I've been thinking about lately, because it's that time of year when people are getting their advanced placement test scores back. And I get lots of tweets from people telling me that Crash Course helped them do well on one or the other of those tests. This is great. Thank you. I give you most of the credit, but I'm glad Crash Course helped. But I also just think this is a good time to say out loud that you're not your numbers. We're trying to sort of understand our own value and our worth and our impact. We look to numbers because they're easy to understand, right? I think that we often draw our confidence from them and when we see a bad one, we lose some of that confidence. And I think that we look to the things that we quantify, whether that's our AP test scores or our net worth or our BMI or our, like, how much we can bench press. I think we look to those things because they're easy to measure, not because they're actually good surrogates for our value or how confident we should be and how much we should like ourselves. There are many things that are more important that are just much harder to measure with numbers, like how good you are at communicating, how driven you are, how much you care, how thoughtful you are. Whether or not you are willing to take on or even really want to take on things that are difficult for you. We don't even try to test for that stuff. We just hope that the things that we do test for are kind of, like, include all that stuff inside of them somehow. John, you made a video this week that had, you know, not a very interesting thumbnail that didn't have your face in it and the title was Civil Twilight, which is not, like, ooh, clickbait. And of course, that video got way fewer views than the average vlogbrothers video. But if you just measure that by the number of views, you miss the fact that, like, the people who watch that video got a very different experience. Like, I watched that and it made me think so much more than the average video I watch, and it made me proud to be your brother. It's so easy to look to numbers to define other people and to define ourselves as if we're earthquakes. But, man, and I know people have heard this before and said it in a bunch of different ways and in places, but when we define ourselves that way, it is bad. If humans are seven billion earthquakes on the planet, I want to think less about how big my shake is. And more about what my shake does and who I shake it with. And John, I'm happy to be shaking it with you. I'll see you on Tuesday.
