Yes, so definitely the focus on the execution of the plan. I think in terms of what we're working on, it was pretty clear and everybody was in line and we knew what we were setting out to do. What's really surprised me is the pace at which this has been achieved. When you think of it, between what we said at the Analyst Day and today, which is the six months or six, seven months ago, it's not because we've won major new contracts, right, it's not things that fall out of the air, it's really working on things that are within our control around efficiencies in the plants, working on the cost base, making sure we align our resources to where the leverage points are, getting rid of some of the things we're doing in the past that had limited value, and focusing our resources on making our processes work better, reduce our cost base and simplify this organization. So I think what has surprised me is not so much content or things that came out of nowhere, it's really focus and dedication of the team in making it happen in a quick fashion. And then the other thing too is, when you look at Project 2019, which we are announced back around those days - certainly expanded upon at the Analyst Day, initially when you - you basically think about the psychology of an organization you come up with a plan, you have people work very hard to produce a plan and you look at the plan and you say, well, guys, fantastic, I appreciate all the hard work, this is a tough hill to climb, but guess what, it's not enough and here's another layer and we've got this exciting project for you and it's Project 2019. It wasn't exactly clear to me that people would embrace it and make it happen that quickly and again that additional layer of initiatives that people are delivering upon really gives me a good feeling. So, yes, that's kind of the surprise, it's more about the pace than the actions themselves.
