Personally for me,
I work regularish hours 0630 start finish 1600-1700 Monday to Friday and am 10 mins from home. I’m well paid for the job, not stopped breaks and have been doing the job long enough to know most of the places, people and equipment I have to deal with.
It’s still varied enough to be different and not monotonous. It’s can be a difficult, dirty and demanding job but those factors lessen with experience. I quite enjoy a bit of a challenge, working out how to load all the bits together safely makes it more interesting.
It’s never going to progress any further, but hey guess what I’m not bothered. I’m not rich, never will be but have a good standard of living and I enjoy my family.
If it’s not for you so be it, go and do something else. One day maybe I’ll have had enough and will pack it in but currently I;m happy enough.
