I get extremely stressed out by anything where I have to talk about myself or my work, honestly. I see other people's polished Branding™ posts and I wish I could have that on some level,1 but what would I talk about? I feel like everything there is to say about my creative work is in the piece. I could say how I made it or what I was going for, but I don't know how to make that interesting or pithy, or what people would want to hear.
As for me outside of my work... I mean, how does one define a person? I don't define myself by my current job. I've tried fandoms; they make me anxious. I don't follow a sports team. We're all blobs of probability and tendency and circumstance and you want me to fit all that into a short-and-sweet bio that makes me sound likeable?
So even though I know there's no real limit on what I can post, I feel weird about posting anything.
1 Maybe it's not so much the "brand" as it is the implication of understanding what your own deal is so thoroughly.
