A few years ago an entrepreneur who had given up a lucrative job to pursue an idea for a tech company. He was making a very high salary and I asked him where he had found the courage to quit. He pulled a paper from his bag and passed it across the table. I immediately recognized it as the printed text of the Jobs commencement speech. “This gave me the courage to follow my heart,” he said.

A great speech can give people courage they didn’t know they had. The Jobs speech has been inspiring people for a decade and will continue to do, convincing many more people to “Stay hungry. Stay foolish.”
