Wow, you had some hard jobs Rob.
I was entrepreneurial from an early age (around 9 years old) selling weeds from a stall outside my home. Well, some weeds have pretty blooms. I think that I made one sale to a little old lady.
As a teenager, I started a window-cleaning round, but didn't realize that existing window cleaners jealously guard their turf. So I got threatened with a knife in one area but blagged my way out saying that I had only been canvassing for work even though I had done some work. And then I heard that another guy was looking out for me so decided to quit.
I did farm work - baling hay, where I was the human fork lift, loading the truck with the hay bales, then piling them up in the barn. This was hard work in heat and dust, but I did get to fool around with the farmer's daughter up in the hay loft
Then I was a gardener at a pub. Probably the worst job since I could tidy the garden in no time and get bored. Plus I didn't have any interest in gardening or knowledge about flowers. But I did get my first taste of real ale, which was amazing after my previous experience of cheap canned beer that my dad used to buy.
I don't remember what I was paid for these jobs, minimum wage I guess?
After graduation I got my first full time job in the electronics industry where I had a good career for about 18 years. I changed company many times because I tend to get bored after 6-12 months with the same firm. So if I went back to that I would definitely become a contract worker.
Now I'm building up a language teaching business, and doing my online stuff.
I don't put up with jobs that I dislike, so I've only endured bad working environments for short periods as I formulated an exit plan.
3 times in my career, I felt abandoned, with no direction, so it was painful to endure 8 hours of tedium in the office cubicle, and put up with the commute to the place of tedium. But mostly, I had a good time at work.
