job careers

Well I'm really not going anywhere where I am right now at my job and I have no idea what I wanna do as a career...

I want to do something that I know I won't be effected by the economy I.e get laid off, loose work hrs, etc something I know I can benofit from, and has good benifits...

Right now I make 11.40$ an Hr 40 hrs a week as a cook at a hospital well 330$ ish a week isn't really cutting it of course it is now due to living with perents and havn't a family yet, and the benifits are good but what is out there thats better.

My friend use to do refrigeration and he made 700$ + a week and saved, saved, and bought a house , built a nice tocoma truck, and owns a infiniti as a dd..

I'm thinking about refrigeration it sounds very Kool and pays very well. What careers do you guys do. Or what are some that pays well with good benifits.. I'm willing to learn and work hard as long as it pays off...
