When Marconi suggested the possibility of wireless transmission of sound (the radio),he was committed to a mental institution. But people like Lincoln, Edison, and Marconi were strongly motivated. So they didn't give up. They somehow knew that the only real failure is the one from which we learn nothing. They seemed to go on the assumption that there is no failure greater than the failure of not trying, and so they continued to try in the face of repeated failures.
