My father died when I was nine months old, making my mum a single mother at the age of eighteen. While I was growing up, we lived a very hard life. We had little money, but my mum gave me a lot of love. Each night, she sat me on her lap and spoke the words that would change my life, "Kemmons, you are certain to be a great man and you can do anything in life if you work hard enough to get it."
    At fourteen, I was hit by a car and the doctors said I would never walk again. Every day, my mother spoke to me in her gentle, loving voice, telling me that no matter what those doctors said, I could walk again. She drove that message so deep into my heart that I finally believed her. A year later, I returned to school — walking on my own!
    When the Great Depression hit, my mum lost her job. Then I left school to support the both of us. At that moment, I was determined never to be poor again.
    Over the years, I experienced various levels of business success. But the real turning point occurred on a vacation I took with my wife and five kids in 1951.I was dissatisfied with the second-class hotels available for families and was angry that they charged me an extra $2 for each child. That was too expensive for the average American family. I told my wife that I was going to open a motel for families that would never charge extra for children. There were plenty of doubters at that time.
    Not surprisingly, Mum was one of my strongest supporters. She worked behind the desk and even designed the room style. As in any business, we experienced a lot of challenges. But with my mother’s words deeply rooted in my soul, I never doubted we would succeed. Fifteen years later, we had the largest hotel system in the world — Holiday Inn. In 1979 my company had 1,759 inns in more than fifty countries with an income of $ 1 billion a year.
