Also consider a healthcare career. As a teenager, I wanted to do computer science/engineering, and sometimes I do wish I had stayed on that track. But now, as a nurse, I could get a job in any state in the US by tomorrow. I dare you to try to find a hospital that doesn't have open nursing positions. Even when the economy goes down, people still get sick. Even if society collapses, the knowledge/skills will be useful.

And if you don't want to change diapers or deal with blood, there are still options; I'm in psychiatry and rarely have to deal with either.
