I have been for a long time particular about grammar and such, because for some reason it seemed to come naturally to me and I understood the difference between saying something well and not. And I got derided as a child in school for being good at it. But recently I finished a book on ancient Mesopotamia and understood the author's point how scribes of those times, the ones who understood how very well, after years and years of training to write in their very complicated ways, actually made it harder to change over from writing that did not use an alphabet, but instead a kind of picture-writing, to a form which actually had an alphabet. So I guess there are drawbacks to learning something too well!
