Most people will tell you that you can't be passionate about being successful (whatever that means) nor about being happy. Passions are like: real-estate (Donald Trump), sports and media (Ted Turner), human rights (Nelson Mandela), the ecology (David Suzuki). I'm passionate about finding ways of using IT more effectively and in ways to reduce our impact on our environment. Some people are into flying, teaching, healing, etc, etc.

Now, it's our turn: What are you passionate - or at least very interested in?
