What does God want me to do??????

I've often wondered what I would do when I 'grow up.'
When I was really little, I wanted to be a vet. After all, I love animals! But then I realized being a vet involves surgeries, blood, guts, and.....putting animals down. So that dream faded.
Then I wanted to be a missionary. Imagine, going to a far-off country and bringing people to God! But I didn't really want to learn any crazy languages, nor go somewhere far-away from civilization.
More recently, I've had a dream of being a teacher at a private or Christian school. I love kids, and love teaching, so I've become very interested in education.
But what does God want me to do with my life?

I wasn't really sure, until about a month ago.
I was at church, and I picked up a flyer. The advertisement read like this: TEACHERS NEEDED FOR INTERNATIONAL CHRISTIAN SCHOOL IN AFRICA.
I was intrigued, so I picked it up. Upon further examination, I saw that this job combined two of my dreams: Being a missionary and teaching!
I've since then pinned the flyer on my bulletin board, and I see it every night and every morning. Could this be what God wants me to do? Be a missionary and a teacher, all at the same time?

I still have quite a while before I find out, I suppose. Until then, I'll just have to keep learning and trusting in God.
