Nobody can deny that Steve Jobs has changed the way we interact with technology. One of his best videos was his commencement speech at Standford University in 2005.
I think that the best segment from the speech is: “Your time is limited, so don’t waste it living someone else’s life. Don’t be trapped by dogma – which is living with the results of other people’s thinking. Don’t let the noise of other’s opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary”
