This is Memorial Day weekend, so I want to spend the entire week focusing on America and its greatness, and I really want to focus on the quiet things that made America so great. I've already talked about how the hard workers, the people who worked in the factories, and the teachers are so critical to America's success, and that, of course, is you, but there are other things I want to focus on as well. I'll be back with one of those right after this.

America works because hundreds of millions of people quietly do their jobs every day. Electricity turns on because someone maintains the grid. Food arrives because the truck drivers keep moving. Flights operate because mechanics inspect the aircraft at two in the morning. The freedoms that we depend on, enjoy, and often take for granted are protected by people whom we will never know personally. That's very humbling.
