Yeah, David. So, the way we're thinking about it is, marketing, combined with our CRM is a real opportunity to grow the business both with new users and existing users. And then, as we think about our digital business, one of the things that I'm really excited about is our order ahead business, as we continue to get people into our digital system, they really see the benefits of, one, joining the rewards program, but, two, just the convenience, the ease of access by using whether it's the website or the app. So, we believe there's going to be continued growth there. And then, obviously, I continue to believe that there is more growth just running our restaurants better. As we continue to improve on our throughput, that just basically continues to be a multiply effect, right? It's like, carne asada, the digital business, none of it will be nearly as effective if we don't have strong execution on the basics with our restaurant. So, I feel like every one of these calls, people are always like, what was the one thing and what's the one thing to drive comp going forward. I really continue to believe the strategies that we've outlined all contribute to our ongoing growth model. And we've got lease on – some will provide more at certain times of the year and others will provide more at other times of the year. But, in the end, that's why we had the year that we had, and that's why I believe we'll continue to perform going forward.
