pursuit of passion

I think Passion is one of the hardest things to write about. Not the passion that I have, but how to get passion. Sometimes I think you either are or aren't. I do believe someone can be inspired by someone else and catch passion, but I think it has to be witnessed first hand, like when someone talks face to face about it or you just see the fire in someone as they talk to a group. But writing about it and trying to inspire? Not impossible but it does seem difficult to me.
