As a young man, Howard White of Portland, Oregon, was a basketball star at the University of Maryland and was drafted by the NBA, but knee injuries interrupted his career. White is now vice-president of Jordan Brand for Nike Inc. He considers himself a fortunate man and thinks that his good fortune has been aided by his belief, that is, small things in life, such as a simple polite greeting, can lead to large outcomes.
    He works at a company where there are thousands of employees. Though he doesn’t know them all by name, he knows a fair share of them. And almost all of them know him. It’s all based on one simple principle: he believes every single person deserves to be acknowledged. For him, that begins with "hello."
    One day when White was about 10 years old, he was walking down the street with his mother. She stopped to speak to Mr. Lee. White was busy trying to hit the "0" in the stop sign with a rock and didn’t pay any attention to Mr. Lee. After they passed Mr. Lee his mother said something that has stuck with him from then on. 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 guideline for Howard White and the foundation of who he is.
