Yes, sure. I appreciate question, Ryan and I'll jump in and JB may want to add. The progression to the mid-teen ROTCE, I think you described it really well, it will be revenue driven positive operating leverage, I just mentioned the NII trajectory next year, which will be, progressing into the mid-teen, coupled with the fact that we'll continue to see other revenue expand over time, minus some of those one time. So when you wrap that all up, we're expecting total revenue in next year to be around 9% or so. And so really nice positive operating leverage driven by that revenue growth and coupled with the fact that on the credit side, we do expect that to migrate more towards normalized levels as we exit 2021, and into 2022, and 2023. So those are some of the big dynamics there. And I would absolutely expect that the 15% is sustainable. And I think that's due to all of the drivers that we kind of just described this morning around consistent customer growth, continued value add across every one of our businesses. We don't see any signs of stopping in the auto segment, continuing to grow relationships, deals per relationship, and just our positioning in the market couldn't be any better than it is today. And we don't see any sign of that stopping over the next several years. And you slide over to the deposits business. And you look at the 10 years of sustained customer growth. And really the transition from customers that were chasing price to really now customers that have bought into the digital transformation. COVID have certainly helped with that. But I do think that is a permanent shift in customer just propensity to purchase digitally. And with cash rich balance sheets across direct banks, as well as the entire industry, I don't think we're going to see a lot of appetite around increased pricing on the deposit side. And then last, but certainly not least, just the rapid scaling that we've seen in our newer customer segments. Every one of our newer customer segments is up 70 plus percent this quarter. And you just continue to see that added value, and the added ability for us to diversify our revenue into these higher return products, whether that's our lending, our invest product, as well as mortgage as well. So maybe a long winded answer, but bottom line here is really confident in getting to that 15% in short order, and sustaining it over the long term.
