How to become a teacher?

After helping my elementary cousin with a few simple math questions this certain feeling befell me. It felt... satisfying in a way. To impart knowledge unto the next generation feels good. For as long as I can remember I've always wondered and dreamed about what I wanna be when I grow up. Do I want to be a policeman, fireman, dentist, accountant, or maybe even a teacher? I honestly don't know what I wanna be... I want to do something that's satisfying outside The Cube and right now I'm at teaching. I want to become an elementary school teacher, but I don't really like working around such a big group of people. Maybe something smaller like working at a preschool? What do you guys think? Right now I'm thinking of anything to do with teaching, and children.
