As for me, I've just graduated from highschool in November, and so where you've got your life figured out more or less, my life is not figured out at all. ~fun
I think I might do actual rocket science. Sending stuff into space. Stuff that's personally really fascinating. Of course that means more school, but oh well. As for yourself, don't worry about it. There's plenty of time for you to figure that stuff out. This has been a recent revelation for me, so I'm sure you'll get it all sorted out when the time comes. Good luck!
