Defensiveness
It's so funny, going back to school, starting a new profession, and learning to write a whole different way again. I remember seeing someone online (probably one of you lovely bloggers out there) talking about how when students have to tackle a new subject, their writing skills tend to deteriorate initially as well. That is, when you're tackling something hard and new, it's hard to write up to the level of skill you learned for another context.
I completely feel myself doing that; it's harder for me to avoid problems in legal writing that I know I routinely avoided in historical writing. But even more so, I've regressed in terms of my reaction to feedback!
I think by the time I left academia, I'd got pretty good at not taking feedback personally (or, I should qualify, not taking *reasonable* feedback personally. Petty, nasty feedback is something else entirely). I whole-heartedly subscribe to the idea that if someone reading your work makes a comment in which they appear not to "get" what you've written, what to take away from that is that your writing in that section needs to be clearer. But now that I'm working my way through a new style of writing, when people give me feedback on something - say, suggesting that I need to emphasize X - my automatic response is, "That's not what I meant! I wasn't talking about X at all!"
I may be older than many of my fellow students, but I am not older in studying the law, and I react to setbacks or criticism just like the newbie-est of new students. It's a little weird.
