I lucked out. My first real job (I consider a real job to be one that the government keeps track of, not really mowing the neighbors lawns) to the one I got when I was sixteen. My stepdad had a friend who owned a computer tech shop. They needed some summer help so I managed to get hired. I ended up staying there for two and a half years building computers, troubleshooting and doing phone support (which was the worst, by the way--it sucks enough if you're male but since I'm female, I got the, "Maybe I should talk to a real technician, lady" rude sort of people who assumed I couldn't do my job because I was female).
Great experience.
