Starting your own business would be amazing just for the fact of removing managers and their ilk from the equation.
My Father cut his teeth in London, starting out by shop fitting and it was decent money back then, not sure nowadays. My brother started out house bashing locally, specialising in domestic wiring but for less mular. Both jumped ship (pun unintended but I will take it) to the Industrial sector after a few years, became well-off and enjoyed half a year on annual leave, every year. Once you have sufficient experience the options for sparkies are abundant and the world becomes your oyster. Bastards
