I don't think excitement or passion or pride require fanaticism either. When I ask my friend who paves road about a project he's particularly proud of, he'll have an answer and it's not because he's paving roads in his spare time.

What is different about some other professions is that there are ways to develop that passion during apprenticeships or entry-level jobs while learning from those with greater experience. Mastery is far easier to acquire with a teacher on hand who can give timely, guided feedback and correction.
