How do I know who I am?

...Very often find confusion
In conclusion I concluded long ago...
In my head are many facts,
Of which I wish I was more certain I was sure!
Is a puzzlement!
- The King and I

I certainly know how the king felt in that song. It pretty much characterizes my life at the moment. Mostly it relates to the things that I thought I wanted to do with my career. The "What I want to be when I grow up" type stuff. I don't know if I ever have known what I wanted my life to look like when I hit 20, 30, 40 or whatever. The one thing that I have often come back to is I want to flex my creative muscles. The biggest problem with that is that my creative muscles are the equivalent of a 98 lb. weakling that is trying to show off in front of the mirror until Hercules walks in the door. I have been reminded so many times that my version of creativity is sorely lacking compared to most people I know who may stand a chance at pulling in a job in those fields.

How do I even start attempting to figure out what I enjoy enough to identify a career path to tread? Where does one begin when they have to go back to the beginning? What does the step one look like for something like this. I don't think I ever knew.
