I'm closer to my 30s in age. I have a degree, but don't have skills that employers seek out for. I don't want to end up working dead end jobs for the rest of my life "searching" for a career.

I have tried programming but it requires a certain mind and i don't think i can "fake it, until i can make it." I believe IT Security is similar.

What are some careers where i can get into at my later age make a living off and potentially retire well off? I don't expect any answers here, because there probably isn't, but in the offchance there is?
