When I was a salesperson working for Radio Disney, back in 2001, I was assigned the Burger King account to call on. I called Brenda Fuentes, my prospect, 37 times over 6 weeks. After 30 calls, my manager told me to stop calling and move on to another account. I kept calling, until she finally picked up the phone, on the 37th attempt. We had a great conversation, I set up a meeting to pitch her, I closed the Burger King business, and I earned a $20,000 commission check.
