If I had to choose between being good at writing or being good at math, for example, it'd be writing by a long shot. I have a lot of fun doing algebra, but nothing feels better than taking the massive jumble of floating nonsense out of my mind and putting it on paper.
Don't know if this would make sense to anyone, but teachers tend to kill my talent.
I was sent to a school for so-called 'gifted' art students when I started grade 1, went to some weird gifted art camp in grade 6, and then when I got to middle school my Art teacher absolutely hated me and I lost all interest. I even managed to fail the subject for the next three years that I was forced to take it. Now I can only do terrible drawings, and I cringe when I see paints, colouring pencils, markers, and the like.
And right after I started hating art I suddenly got all interested in writing. So instead of being pestered about my artistic abilities, I was getting unwanted attention for my out-of-the-blue writing skills. My homeroom/English teachers especially liked using me as an example, and having 24 sets of eyes focused on me definitely isn't something I like. Then once I hit grade 11 I got an English teacher that (this time I'll say...) strongly disliked me because I, according to her, had no sense of humour and no motivation for success. I got dismal grades all year (the exams were the only things that saved me, oddly enough), and now it takes me forever to even think of what to write.
Weird, but true.
