One thing I've been asking myself is, if I had money or was a success, would I still do X? In my case move, go to college, or in your case escort or programming or other?
Money is all about adding value.
I'm introverted as well, but I think a lot on green techs or sustainability, or building something. That and green energy as well as physics etc.
One way is figuring out what people want or need and giving it to them. That is what Steve Jobs did.
I wish you luck in whatever you decide
