I'm not 100% sure, I'm generally an optimistic person, so I'm not generally certain I could -- I'm saying that I could validate what you're saying there. What I can say is clearly where there is probably more confidence is that, and this is something we tried to even bear out in our presentation, is that what's crucial about the fourth quarter that we just experienced and by exceeding pre -pandemic levels, particularly including command center, means that we are -- we've demonstrated now over, let's say, a 10-quarter period that we were able to retain the business that we acquired. And the same is true with Snelling and with LINK. What that really means from a -- to me is that we've done a really good job retaining what we acquire and the real demon in service company acquisitions is retaining that business because it's service related. So when you lose people, you lose business. And with a lot of these acquisitions people go out and then the top salesperson quits, the good managers quit because they don't like the new culture. Well in our case, typically, the old -- the incumbent management team is the same people who are sticking around. And -- so if I have more confidence, it would be simply because I do believe our model has been validated now over really 10 quarters. And so in that respect I do -- I guess maybe that's come out -- it's not intentional, it's just I always believed it was going to happen, but of course it's kind of funny when you look at the history of what happened with the company, it's just -- we went, we did the acquisition, the merger, had a bunch of costs the first two quarters, and literally finally it's like, yes, we got this stuff behind us, and then the pandemic hit literally in the first quarter when we were ready to hit good things. And so it's been a long journey that way, and I do feel that we're on -- a lot of things could happen, oil could go to a $150 bucks a barrel or inflation could go to 12%. Lots of different things that can happen that can mess things up. But overall, again, I do feel like our business model has been validated. And -- which means there's no real limit to what we do.
