Electronics has been a hobby for me since my early teens, went to college for a couple of years until I could take it anymore. I work in a warehouse, where you'd think any moron could do my job, but apparently there are subcatagories... Don't need to think much about what I do, so plenty of time to think about other things. Lots of exercise, don't need spend my free time working out, pay and benefits not bad and actually better than most office jobs.
Basically, I learn about what I need to know to complete projects. The theory and math was too many years ago, but I know where too look.
