Hi Formerbrother,
I was a window cleaner like yourself when I was in my mid 20's, and still a JW, but I had the great fortune to fall off my ladder and fracture my back. Because of that accident I was able to get free back-to-work training so I took all the computing courses I could which led to my first office job and for the next 20 years I have been continuously employed in jobs with pension contributions, paid holiday and sick days and all the other benefits.
Because of my JW upbringing I never went to university or even Sixth form, but I am now a database developer with a lot of experience.
I don't advise the falling off a ladder approach but I would say to get on some college courses and get out of window cleaning. If you love window cleaning then maybe look at small business management and bookkeeping courses and become a window cleaning company manager and build an empire!
Why do you still go to meetings? Do you like being beaten with a stick?
