Many years ago, when the movie "10" starring Bo Derek aimed to portray a woman who was so beautiful she was a "perfect 10" in all ways, a national news team decided to try an experiment. They searched fashion photos, movie star pictures, and many other sources to find "the perfect lips" and "the perfect nose" and "the perfect eyebrows," and so on, for chin, hair, ears, and cheeks. They said they would photo shop them together and present the truly perfect woman. The result was not at all what they had intended.
In sports you can do the same thing. Bring together the best basketball center, the best guards, the best forwards, and you won't necessarily have the best team. Thinking otherwise commits a classic philosophical error called "The Fallacy of Composition." Or in another phrase, the whole can be greater than the sum of its parts. Or lesser.
Harmony is an important ingredient in greatness of all kinds. Do you have it in your life? In your work? Among your actions? In your family? On your team? It's a key to beauty and excellence.
