As for linguistics:
I won story competition with moralful short story when I was in elementary school. It was about someone eats bananana but throws the skin on the street, make it slippery. I didn't remember its detailed story.
I was chosen by a teacher as a worthy student, a school representative, to compete in General English competition when I was in junior high school.
Not really an achievement but I used to discuss words definition. Sometimes discuss the origin as looking for its definition. I often did it with my mates in my univeristy student senate, sometimes with my mates in my department or my brother when I went home.
I also started some stories, none of them finished, but gone. I really hope I can find those, or maybe later finish a new start.
