There are lots of things I'd be equally satisfied with and good at doing, but there's nothing that grabs me by the throat and says ME!ME!ME! Which is why I'm floating around in career limbo at the moment.
I was in career limbo (well, knowledge-about-what-I-want-to-do-wise, anyway) until I was 21 (I'm 24½ now). So, I never took any classes in high school which would have helped me with the career I now know that I want, and playing catch-up now, when I have to pay for schooling is extremely difficult.
