Yes, it's a good question, Damian. I think the way that I think about it is, from the time we spent to where we are today, we've driven our EBITDA margins from approximately 6% to approximately 13%. So we're sitting in low-teens, right now. We really want to get that the high-teens. And we believe we can do that and really the primary way for us to do that I believe is through RCI initiatives. At the end of the day, we're all in competitive businesses, we all have inflationary pressures. If you are not doing CI, you're actually going to be moving backwards. But the way that I think about it at a high level framework is we push all of our businesses to expand their margins 50 basis points a year, and in order to do that, you just can't do it on your good looks right, you have to have a plan, you have to have a strategy and we actually think LEAN and AD-20 are the best tools for us to really drive value. Now, if I look at where we are today as an enterprise, I do believe we have built a really good business system and how we run the company. Everything we do from our planning, to our strategy, to our goal deployment, our KPIs, the integration processes have been excellent. And I would argue that's really a best practice and what we're really focused on doing, is bringing in the CI leg to our business system. it's a cultural change, the tone at the top, it's how you behave, it's how you act, it's how you reinforce it, it's not something that happens overnight, but it's a process and we actually are very excited about this journey. So, yeah, so I think COVID, frankly we had a lot starting at the beginning of this year, which COVID took a lot of our programs and slowed them down due to, frankly due to travel. And you can't do as much training, you can't do much as travel but we feel good about our direction and it's something you're going to hear us talking about a lot more. But then again, we haven't put a number in there, but the way I would think about it, Damian, is we have to do this to drive our margin tire and this is the primary tool and not enough. Jamie, Paul, you guys have, anything else you'd like to add there?
