How do I get pion for something?

I'm 24 this year. And I can only have a couple of things in my life that I can say that I am pionate about. Listening to music is the only thing I have that I am pretty sure I will like as much today as I will 50 years from now if Im still alive by then. I look at other people and get envious of the fact that they have something that they are good at because they are so damned pionate about it. The question really is how does a cynical such as myself find something that can light my fire? I want to do something that will get me going. Please, give me your suggestions.
