Architect Frank Lloyd Wright once told of an incident that seemed insignificant at the time, but had a profound influence on the rest of his life. The winter he was 9, he went walking across a snow-covered field with his reserved, no-nonsense uncle. As the two of them reached the far end of the field, his uncle stopped him. He pointed out his own tracks in the snow, straight and true as an arrow's flight, and then young Frank's tracks meandering all over the field. "Notice how your tracks wander aimlessly from the fence to the cattle to the woods and back again," his uncle said. "And see how my tracks aim directly to my goal. There is an important lesson in that."

Years later the world-famous architect liked to tell how this experience had greatly contributed to his philosophy in life. "I determined right then," he'd say with a twinkle in his eye, "not to miss most things in life, as my uncle had."
