    A few years ago, my wife, Sue had some serious health problems. She had suffered surgery after surgery and had also put on weight. Diets had not helped her and she suffered constantly from undiagnosed pain. One day the whole family sat down and drew up a “wish list”. To our surprise, one of Sue's items was to run in a marathon. Given her history and physical limitations, I thought her goal was completely unrealistic, but Sue became committed to it.

    She began by running very slowly and every day she ran just a little farther than she did the day before. Soon she could run three miles. Then five. Sue kept practicing and longed to run in the St. George Marathon in southern Utah.

    On the big day, I parked our van near the finish line, waiting for Sue. The rain was steady and the wind was cold. The marathon had started over five hours ago. The fast and strong competitors had finished already. Several cold and injured runners had been transported past me, and I began to panic. The image of Sue, alone and cold, off the road somewhere, made me sick with worry.

    Another hour passed and I spotted a small group running up. As they approached, I could see Sue, in the company of three others, and a woman in her twenties was near Sue. It was obvious that they had become friends during the race. I could see her begin to struggle. But when the finish line came into sight, she confidently even happily picked up her pace the last hundred yards to the finish line. Few people were left to congratulate my wife. They openly praised and embraced her, “She made us believe we could do it,” her new friend stated.

    From then on, she was carrying herself differently. Her head was more upright. Her shoulders were squared. Her walk had a new confidence. Her voice held a new, quiet dignity. It was not as if she had become someone new; it was more as if she had discovered a real self she had not known before. It was perseverance that made her realize she was an undiscovered masterpiece with a million things left to learn about herself. She truly liked her newly discovered self. So did I.

      Dolores grew up in California. She was a good student and liked school. After she finished high school, she went to college and studied to be a teacher.

        Dolores decided to stop teaching so that she could spend more time helping the farm workers and their families. One thing she wanted to do was to get more pay for farm workers so they could buy their children the things they needed.
Dolores knew that many farm workers moved often from one place to another to help pick different kinds of fruits and vegetables. She began talking and writing about these workers. Even people who lived far from California read what Dolores wrote.
      Getting higher pay for the farm workers was not easy. Dolores worked hard to make sure that farm workers got good pay for their work. She knew that nothing would change unless people made new laws to help the workers. Through all her hard work, new laws were made that gave farm workers good pay.
