gfody's description reads to me like a description of genius-level work. it's not "not being able to get your mind off of work". it's, wow, you're a genius for being able to do this at all - it's not some fungible thing anyone could do instead of you. yours sounds like the description of more fungible work, that could be done by someone else and for which hours may even be a good measure. it just doesn't sound like you two are talking about the same thing.
