Great to have Lewis here and, Lewis, everybody talks about greatness. When you talk about greatness, you say it starts when you walk into a room. How is that? You got to start with the do/rway test. You know, we are a cell phone culture so we're always looking down, right? But it's hard to connect to people when we're looking down. Every time I walk through a doorway I elevate my chest and look up and look people in the eye so just like that, look people in the eye and connect. That's the great way to be great. What I want you to do not stand up, stay seated but ago like you're walking through a doorway and look people in the eye. That's it. It's empowering. Super empowering, gets your confidence up. Gets your energy going. We have whiteboards here. You will give us three keys to greatness. Three little things we can live by every day That's it. So what is your first -- snrs key number one, key number one is gralt today so I want to you write down one thing you're grateful for right now. It could be that you're on "Good morning America." That you're in New York City, about your family, about your health. Something you're grateful for, one quick thing. You write it down as well, Michael. Go ahead and hold up your whitebo whitebo whiteboards -- your wife. Trip to New York City. Family, health, opportunity, family, family, faith. Houston astro, there you go. Tigers, awesome.

I'm right on time but I could be better. Thank you, guys. You can put it down. The third. The last one is simple. If you want to be great, give back. Okay. It could be giving back to a family member, a friend. It could be -- you don't have to write anything down here but think about an area you could give back.
