Right now I live in Germany, and speak pretty ungramatically, but from being here I copy a lot of everyday idiom without really understanding it. So what I would like is the opposite of what you are looking for: confidence that my German sentences (especially written ones) are formally correct.
I don't mind if that makes me look like a well taught foreigner. Right now I sound like a badly taught foreigner.
