I think the term "passion" has been abused a lot to mean being excited and loudly proclaiming "I am so passionate. I love it.". I am not likely that and I dont expect to be like that. With passion I mean the desire to learn and do a good job just because it makes life more interesting. I work around 40 hours a week and I try to make this time as interesting and enjoyable as possible. To me that means to do a good job and improve as much as possible. Once I am on my way home I don't think about work anymore.
Also, people who stayed in this industry long do care generally.
There is also something good to he said about people who understand importance of boring tasks and negotiation and planning and process and do those boring tasks.
