I was a window cleaner for 8 years 2003-2011. Wfp from 2004. Felt like I wanted a career. Sold the business, lived off the proceeds for 1 year whilst I did my teacher training ( I already had a degree in History).
I took a huge walloping pay cut which only grew in 1.5-2k increments until by 2021 I was earning the same as I was in 2011. I was stressed, tired, had a boss, had deadlines, had to do as I was told and in 2023 was done. I didn't even finish my last year as a teacher - quit before the end of the school year and window cleaned.
I'll tell you one thing, I never want a boss again. Not saying I didn't meet lots of people, learn loads of skills and discovered a talent for writing plays and stories and putting on plays with props and lighting etc, but seriously, give me some windows to clean and be outside all day over that.
