Oh, yeah, absolutely, absolutely. And I think the principle here is, again, I was telling you this idea that memories can compete with each other, right? Right. Well, I like to use this example, and maybe someday I'll regret this, but I've used it a lot recently. Imagine if this were my desk, it could be cluttered with a zillion different things, right?

So imagine it's just cluttered with a whole bunch of yellow Post-it notes, and on one of them I put my bank password on it, right? Well, it's going to take me forever to find it. It's just going to be buried under all these other Post-it notes. But if it's like hot pink... It's going to stand out, and I find it really easily, right?
