What do you guys do jobwise

Im getting into my mid-twenties and want to change careers/jobs...

I need something I can get into fairly quickly to maintain my sanity... with minimal schooln/etc.

So any ideas and what do you gents do? If not what do you do and annual salar and job satisfaction, etc?
