I was a nerd in elementary school ... and everything was my favorite subject, except the Sport lesson (which I dreaded so much). 
But I guess what I really loved was the reading part ...
And as I'm still reading nowadays I guess it has something to do with my life.

Early in high school I became obsessed with Mathematics and Physics to the point I wanted to become an Astrophysician or something like this.  

Then I developped my crushes on English and History and one might say it has something to do with what I'm studying now. (Though Political Sciences can hardly be linked to anything you do in High School).
