A job is a job. It's a way to pay for a living, but that's it. Don't let it define your happiness. You work to live, not live to work. Work on what makes you happy. (I love my job, but this is a good reminder that it's not the only thing that matters).
I can't find fault with this. Being that I am a reader and a lover of books, I can relate to using the story as a metaphor for my life. And when people arrive, it's like starting a new chapter and when they leave, that chapter is done.
