Steve Jobs explains the rules for success... (2 min video)

"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 dont absolutely love it, youre going to give up. And thats what happens to most people, actually. 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 didnt love it, quit. Because theyre sane, right?  Who would put up with this stuff if you dont love it? So its a lot of hard work and its a lot of worrying constantly. If you dont love it, youre going to fail."- Steve Jobs
