That's a great question. We're continuing to invest very aggressively, as I indicated in my script, in new growth initiatives, as we always do. That's the vast majority, really, of our operating expenses are going toward future growth and margin expansion initiatives. In terms of margin expansion, they're just across-the-board opportunities that we are executing against. Let me give you some examples, though. It's a fair question. First and foremost, of course, is top-line leverage. Our media margins come into it as revenue grows, and our revenue grows a lot faster than our fixed or semi-fixed cost base. So you have a natural upward tug on adjusted EBITDA as we continue to grow revenue, and we expect to continue to grow revenue double digits. And of course, we do not expect to continue to grow operating expenses at the same rate. Second, though, we have a lot of new media initiatives that are showing a lot of success. We are, for example, growing big, new-scale areas of proprietary media across the company, and especially in auto insurance. That proprietary media has grown very rapidly, is now about half of our media margin, or margin dollars produced from media and auto insurance, and comes in about two times the of our third-party media sources. We are still completely committed to third-party media. It keeps us aware of the market. It gives us a lot of insight. We are a great partner for those third-party providers. But that proprietary media growth, which is a big initiative at the company, is showing great success, great growth, and great margin, and we've got a lot more runway to go there. So that's a big one. We're converting -- another big one is, in auto insurance, we're converting a number of big media partnerships to fee-based relationships, because that better reflects the nature of those relationships. Some of the bigger-scale, lower-margin opportunities, we're going to be converting to a platform fee model. Some might refer to it as a private exchange model, which one of our competitors, of course, is much more active in that market. We have a great private exchange product that's now been adopted by a number of partners, and we're looking to convert some of the partnerships that have lower margin into that model, because I think it better reflects the nature of the relationship and is really a better reflection of that part of the market in which we're happy to participate in and to be more aggressive in. That's going to be a continued good lever for us on the margin side, particularly, again, in auto insurance. On top of the media initiatives, we have a lot of product initiatives going on. We've got new products that we've been rolling out that have more than doubled this year for to serve agencies and agency-like entities, whereas historically we've been dominantly providing our products, of course, to the direct carriers. Those products, again, are growing very rapidly and are coming in at about twice the margin of our historic direct-to-carrier click product. On top of that, we continue to scale our brand new product areas, and they're getting to decent scale now, including QRP and our 360 finance product. We expect both to be better than break-even this year. If they're spending a lot of time and money getting those products to the point where you can scale them, they're getting to more than break-even and getting to good scale and getting to the point we're going to expect them to be inflecting and they've already begun to do so. So, we're excited about those products and their effect on margins. Also, in our personal loans area, we are very early and we're very narrow in our footprint there. We now know that of the over 2 million qualified consumers we see every month in that business, we're only really engaging with about a third of them and a relatively small portion of them do we match to a product. We now know the products that they want, and we're adding those clients and have added a number of clients to better service that traffic flow, which will give us a lot more pure margin on the inquiries we already see and the ability to go out and source even more. So that's an area that we expect pretty dramatic margin expansion in over the next couple of years. And in home services, which is a great business for us already, of course, we're continuing to scale trades we're already in. As we scale those trades, we're doing it in a very smart way by making sure that we're adding clients in geos where we don't have full coverage or we don't have adequate coverage. That gives us better yield, better margin, better media buying power, and up goes the whip from there. Our growth in home services is really focused on margin expanding growth and buying power growth. That cadence is really working very well for us. Across the business, a lot of margin expansion opportunities, a lot of success already. These are not things we're dreaming about. These are things we're doing. A lot more runway on all of them to go.
