> The founder of FedEx actually wrote a business pitch paper for an overnight shipping company. This paper was given a low grade by his professor. He went on to form this company, which become a success, despite this low grade.

Was the paper given a low grade because it was a bad idea or because Fred Smith wrote a bad paper? If his pitch didn’t work, did feedback from the professor help Smith sharpen his idea so he was in a better position to make FedEx a success?
