I am a wife, a professional, an academic and a student but none of these things tell you anything about me. My job is just a job. I love it and it's fulfilling, but it's not 'me'. For example, my colleague is a 55yr old spinster, she has 75 cats and likes to talk about shelving, we couldn't be any more different. BUT, we have the same job, academic credentials etc.
I define myself by the real choices I make, how I spend my free time, the things I don't have or need to do. So...
I am a photographer, writer, artist, story-teller, cook, camper, musician, festival-goer. I make my own clothes and I eat a lot of gingerbread. I'd rather make a card than buy it, I prefer letters to email and texts and I always wear flat shoes. Any one of these small things will tell you a hundred times more about me than the fact that I am an academic librarian or that I am married to that bloke over there.
In fact, though I say I am defined by the things I don't have or need to do, I would say that I actually need to do these frivolous things more than I need to work, precisely because they make me who I am.
Oh and I waffle.
