Yeah. Hey, Mark. I will take this. So, yeah, I guess I would just say, we think we're just scratching the surface of how much bigger our core business could be. And there's no reason to think it could not be double the size that it is today. And then, the question is, well, what would you have to believe? I think the first thing we want to do is to continue to perfect the core service. To do that, we really have to do three things. We got to make Airbnb easy to use, we got to make it more affordable, and we got to make it more reliable. So just for example, starting with reliability. For every person who books an Airbnb, we estimate about nine people are booking hotels. So, if we could just get one of those nine people to book an Airbnb, that essentially would double the size of our business. And the number one reason people say they don't use an Airbnb is, they don't find it historically as reliable as a hotel. That's why we're really trying to elevate the best homes in Airbnb and remove the worst. So, we now Guest Favorites, 350 million nights have been booked in Guest Favorites. We've also removed 450,000 listings. This has created a lot higher customer satisfaction, reduced customer service tickets. And we think over time, more and more people are going to come to Airbnb. So we're going to do a lot more, Mark, on making Airbnb more reliable. On affordability, we know that that's a big driver of growth. Airbnb started as affordable alternative to hotels. We lost, I think, a little ground versus hotels during the pandemic, but I think in the last couple of years, hotel prices have gone up more than Airbnb. I want to call out that as of last month, we have rolled out total price displays globally. So, now, the price you see before taxes in the United States and really inclusive taxes, say, in Europe, include all fees. So -- and I think this is really important, because it drives customers to the best value Airbnb's, which we rank higher and incentivize the best behavior for host. On the usability standpoint, the vast majority of our people come to Airbnb, don't find a booking. Airbnb last year was accessed by over 1.5 billion devices. So, think about like how many people come to Airbnb, they don't find a place to stay. Part of this is having the right homes for them, but also having the right tools. So, we think perfecting the core is a huge driver to growth, but that is really going to be a big driver in our core markets. Our core markets are US, Australia, Canada, UK and France, the four English-speaking countries, plus France, which make about 70% of our growth -- our business. But the more growth markets, emerging markets would be Spain, Italy, Germany, Mexico, Brazil, and then the big four countries in Asia are China, India, Korea and Japan. And these markets are actually growing twice as fast as the aforementioned five core markets. And we're going to step on the gas. And I think that international will be one of the biggest growth drivers that will get us back to double-digit growth on Airbnb. So that's just a little bit. It's really three horizons. Horizon one, the biggest near-term opportunity is continue to increase conversion rate by making Airbnb easier to use, more affordable, more reliable. Horizon two, really is international growth. And then, of course, the longest horizon will be expanding our core business to offering [beyond a place to stay] (ph).
