Hank I'm 33 so about your age too, I don't class myself as a window cleaner but a business owner, I am a mechanic by trade but chose to leave my 70k a year job in 2006 and start my own business. I don't regret it one bit at all, ok for 2 years it was hard graft buildng the business but now I have guys working for me, I'm not on the tools at all and wake up when I want and do what I want and answer to no one, my biggest decision every day is whether I can be bothered to take the ferrari out or not! And believe it or not 9 times out of 10 it stays at home, but I've had it for 2 1/2 years now anyway so novelty has slightly worn off!!!!!
1 thing I will say is even tho window cleaning gave me a ferrari at just passed 30 and lots of time off work and lkovely holidays, I still feel ashamed to say we clean windows
