A lot of the “don’t do it!” brigade on here seem to be approaching the job as if it’s a lifetime thing. There is no rule to say that once you pick a job, you have to stick with it until you retire/die. Once you’ve had enough, make a new plan and get out.
Advising someone to be a sparkie/plumber/brickie etc “for the wages and home every night”, as seems to be the common thing for older drivers to advise younger ones to do, misses the point. What if they don’t want to be an electrician? So they can do a slightly better paid job that they hate, until they retire or die? I guess it makes sense when you look at it like that, but it doesn’t make sense in the first place - because they’ve still got to do a job they hate. If it’s such a good plan, why don’t they stop driving and start doing that?
Nothing is ever going to be perfect, there is no utopia. However, we’ve got a lot of control over our lives, if we take it - but there is a hell of a lot of things set up to make us fear changing our lot.
