"A jack of all trades is a master of none." ;D
I think it might seem like a talented person is talented at everything because a person that is willing to put effort into one thing is probably more willing to put effort into other things, which results in over all higher achievement.
So, outside of comics and art, my academic skills are pretty good- high reading comprehension and writing essays. I've generally found I'm good at explaining things (like finding the right way to re-explain a concept in class to a student that isn't getting it), which is one of the reason most of my jobs have ended up being in education.
Sadly unlike some of you I do not have the music skills. Which has not stopped me from making a bard for a DnD campaign I'm trying to get going with my friends. Imma sing, and they're gunna tolerate it!
