The thing is the only jobs that don't take time and experience to master are McJobs. There's always the occasional lottery. Most of the time you do have to give up some time or money.

I am in IT. When I started I got crap from some people for taking data analyst positions after making double in another industry. But it got me a paycheck and experience. I invested a lot of indie time and eventually some money learning database skills. I even volunteered off hours at a museum building their mailing list. Dumb little project but besides being around art I took the cashier position originally because I could teach myself java while minding the store. Did not have access to a computer at the time so what I learned was concepts. It really didn't take long to surpass that original paycheck. How did I learn operating systems? I took an old Mac and installed lynx and used it for my personal computing. Apple is easy. Unix not so much. Command line is command line no matter what. Since then all of my desktop computers have been bought as components and put together by me. If you enjoy aspects of help desk technical support is more lucrative. That leads to corporate cs which is very lucrative. But yes you will have to put time into learning it.
