College... Career... IM ONLY 15!

So in my computers class we are doing this huge college and career project. I honestly don't know what I want to be when I grow up, and I will probably pick thousands of things before I actually get there. I also here all my other teachers talking about or future and everything. They say how important everything is and how we only have three more years until all this stuff. I hate hearing about all this, growing up, being responsible. It scares me, I'm just a kid.
