Success is a matter of hanging on after others have let go.
When I was with Capitol Records in Hollywood, the Vice President of Special Products shared his belief in the marvels of persistence with me. According to his story, one day, early in his career, while calling on retailers in downtown Los Angeles, he found himself with some spare time before his next appointment, and decided to call on, for the first time, a large department store chain located a block away. When meeting the buyer, he was told there was no need for his product as the chain was satisfied with a competitor's merchandise. The following month, being in the same area, he decided to try again. Once more the buyer told him he was not interested.
