Thomas Edison famously created over a thousand prototypes of the light bulb before finally discovering the commercially viable version that became a landmark invention. But instead of viewing them as a thousand failures and giving up, he is reported to have said, ‘I have not failed ten thousand times. I have not failed once. I have succeeded in proving that those ten thousand ways will not work. When I have eliminated the ways that will not work, I will find the way that will work.’
