Steve Jobs, who revolutionized personal computing, died Wednesday at the age of 56 after years-long battle with pancreatic cancer.

Jobs changed the way the world listened to music, communicated on the phone and used the computer. Among his greatest creations were the iPhone, iPod, iPad, iMac and the series of Macbook laptops that improved the way people deliver work and systemize huge-scale business planning.

Jobs talked about the rules for success at the D5 conference on May 30, 2007.

“You need a lot of passion for what you're doing because its so hard. Without passion, any rational person would give up. So if youre not having fun doing it, if you don't absolutely love it, you're going to give up and thats what happens to most people, actually,” Jobs said.

“If you look at the ones that ended up being successful in the eyes of society, often times its the ones who love what they do, so they could persevere when it got really tough and the ones that didn't love it, quit. Because they’re sane, right?” he said.
