This evening, Apple announced that Steve Jobs, its legendary leader, has died. Watch his powerful talk “How to live before you die” — in which Jobs urges us to pursue our dreams and see the opportunities in life’s setbacks, including death itself.

Tom Rielly, TED’s community director and an early Mac fanboy, writes: “Steve Jobs changed my life totally and utterly (and obviously, I’m not the only one). From the moment he introduced Macintosh with mesmerizing flair, I was hooked by his charisma. I knew that his invention would change everything. Even though I’ve met him only a few times, I felt a deep personal connection to him and his work that transcends the rational. When I heard the news today, I felt physically ill and terribly sad for his wife and children. I will always be grateful to him and the teams he led that brought us the Mac, the iPod, the iPad, Pixar, iTunes … Quite simply he is my hero.”
