I remember one of my co-workers (a developer or engineer or whatever we are called these days) on a particularly frustrating day, smiling broadly and saying "I'm a guitarist. Programming was my HOBBY. I went to school for music. This was supposed to be fun."

What made the comment even funnier is that we all know he loves his work as a developer / engineer. Its almost all he talks about. He followed one passion (music), but the other, more lucrative passion (development) is the one that caught him as a career. As frustrating as that day was, the funny part is that we live for the kinds of problem solving we were facing.
