This thread is so long, I'm not even sure if I already replied!
I started my adult life as a professional studio and concert musician and started a home business (telephone "Message-On-Hold" programs) during those years. Then I accidentally got into large-scale crime investigations for Lloyd's of London, using my knowledge and experience with digital video to collect and enhance surveillance footage from the darndest places all over North America. When all that fell apart in 2009, I spent a year wandering around on my bike, wondering what to do next.
I ended up working for my local township, officially as an audio-visual technician, but in reality, an all-around, go-to guy for anything having to do with computers, proof-reading, building maintenance, or summer concert logistics. Although I earn a lot less now than ever - and the job isn't quite as "glamorous" as it sounds, I am at the peak of happiness in my working life, due, in large part, to the fact that I work within a few miles of home and can bike to work every day from about April to November.
