One of my best abilities is running.
I discovered this ability when I was really young, because my father loved athletics and he saw I was that good really soon. He wanted me to be in a club, but my mother told to him "no", because I was too young to start competing.
Anyway, I must say that I really enjoy it. I feel as if I was a cheetat (maybe I'm exagerating, but it's true, I feel that!). Although I have to train a lot to have this feeling, it's not a problem.
By the way, I don't really think that I would dedicate my life to that, because it's not well paid and because I prefer another kind of job instead. I would leave this as a hobby maybe, I don't know.
To finish with, I can only say running is amazing!
