I have legally changed my real name (front and back). I'm no longer a fabulous young thing, so it may seem strange, but it's something I've wanted to do for ever. It has made me feel so much better in myself.
My old first name was part of my business name. Most students call me by this name and I had intended to retain it for my students, but now find myself reluctant to do so.
I'd love to hear about anyone else's experiences with this.
