Nah, I understand- It does require a certain "mindset". It can be learned, to an extent, but I've found some people find the specific skillset come easier than others.

I've understood webdesign doesn't require as much coding, so it might be worth looking into, but admittedly graphical design was never one of my own strong suits so I can't help you farther much there. There's a definite demand for people who can do it, at least. (Although I am partly afraid it's harder to pull off alone, since barring you do it on a couple specific platforms that "do the programming for you", it usually requires some coding to freelance, otherwise it requires a helper.)
