Uni degree.. hehe i have one in Motorsport Engineering, i also have a HND in Automotive Engineering and lesser Engineering qualifications.
Why am i window cleaning? because i enjoy it! Why am i not using my degree? Because i cant get a job in the automotive sector, and everyone wants "experience" - how they hell do i get that then if i cant get a job!?!?
So unless i want to work as a tele sales operative or insurance claims advisor ( no offy to anyone that does, but id rather kill myself!) Im quite happy to clean windows, gutters and the like.
No, not all window cleaners make £500 a day (wish i did thou) its those lucky ones that work for posh people that have no sense of money that do.
Some of us are actually quite happy earning what we do, working outside in ALL weathers, with numb fingers and toes, including at the weekends, than work in an office or factory working 9-5 being spoken to like a piece of crap by some jumped up manager who think he owns us.
Fair enough cleaning glass isn't rocket science but it is Water Science. If i was to tell my custies about the science that goes behind making water pure, regarding ro and di, id cause them to fall asleep, as all they want is there windows to sparkle, so rather than bore them - i make their windows sparkle.
