I'm always very interested in hearing about another's work, whatever it may be. I'm using the term here to indicate that to which they devote their energy, enthusiasm, and time, what gets that sparkle in their eye when it's opened up, what gets them wound up in a good way even to talk about. For some lucky people, this is their job/career, and I'm way happier for them than I am envious. For others, it's a calling, an outside interest, a hobby, an endless project, what have you. No matter what it is, I like hearing about it, because it's what makes people who they are, I think, or at least more who they are.
What I'm starting to realize, though, is that I don't know what my work is. There are things about which I obssess and/or can't ignore, but that's a more negative valence than what I'm after. Surely I've got work... don't I?
