I think this is a very interesting subject. I don't feel that I have a passion in life. I have pursued my interests, and am doing pretty much what I had wanted to do when I was in high school and college - programming. I have a PhD in computer science; I don't have any interest in being a manager, and I have been about as successful as you can be without going into management in my field. But, it's not the kind of interest that I'd happily work 12 or 15 hour days at. I've always wished I had that kind of drive for the things that interest me, but I think it's just not my nature. This reminded me of the movie "Adaptation", which I highly recommend (the screenplay SO ingenious and quirky!). "Life's passion" is an important theme in that movie. The orchid thief character has the unusual ability to throw himself completely into a certain pursuit for a period of time, and then to completely abandon that interest for a new passion later. I think those of us who don't have a passion, wish we could be that way. But maybe it's a personality trait? I think the best we can do is to remain open to new experiences, and then we can at least remain interested in life, even if we're never consumed by an obsession as some are.
