GEORGE GERSHWIN WROTE great music. At the first rehearsal of Rhapsody in Blue in 1924, the clarinet player played the first notes of the piece as one, long, rising wail, even though Gershwin had written it as individual notes. Gershwin heard it, and immediately said it should be kept that way. He instantly recognized it would be better. He changed the opening of one of the most famous musical pieces of the 20th century in, essentially, no time at all. Are you secure enough in your business to make changes? Gershwin was certain enough of his ability that he could allow others to improve on it. The ability to change is not a sign of weakness. Instead, it shows confidence. Somehow, we’ve turned that around. As Charles Darwin said, ?In the struggle for survival, the fittest win out at the expense of their rivals because they succeed in adapting themselves best to their environment.? Well, I don’t know. I think I’ll stay here in the mud and let those other species develop an opposable thumb.
