I'm currently working to live. I have other interests, and hobbies, etc, but I'd rather be working a job that I can dedicate my life to. The trick is to keep having hobbies and other interests. Like you, one must have Passion for something. there are so many people who become singularly focused on their job that it stifles their creativity, their ability to connect dots in new ways and innovate. There was a really interesting Ideas Podcast on creativity a while back, and the thing I really got out of it was that You need to know your topic inside and out, learn everything around it, tangential relations, etc. - The go do something else so that your brain can make connections.
