    I work at a company where there are lots of employees. I can’t say that I know them all by name, but I know my fair share of them. I think that almost all of them know me. It is all based on one simple principle: I believe that every single person deserves to be acknowledged, even though it is only a smile or a nod of the head.

When I was about ten years old, I was walking down the street with my mother. She stopped to speak to Mr. Lee. I was busy throwing stones at the stop sign. I knew I could see Mr. Lee any old time around the neighborhood, so I didn’t pay any attention to him. After we passed Mr. Lee, my mother stopped me and said something that has stuck with me from that day until now. She said, “You let that be the last time you ever walk by somebody and not open up your mouth to speak, because even a dog can wave its tail when it passes you on the street.” That phrase sounds simple, but it’s been a guidepost for me and the foundation of who I am.

At work, I always used to say hello to the founder of the company and ask him how our business was doing. But I also spoke to the people who cleaned the buildings and asked how their children were doing. I’ve become vice president, but that hasn’t changed the way I approach people. I still follow my mother’s advice. I speak to everyone I see, no matter where I am. You will realize how powerful it is just to open your mouth and say, “Hello.” I’ve learned that speaking to people creates a pathway into their world, and it lets them come into mine, too.
