I don't remember exactly how or when, but I was definitely told by my parents to look after myself first and foremost at some time during my teens, both in terms of health, finances, sex, etc. It was probably part of the "sex" talk or around the same time. Basically all about self respect, self reliance, etc., and never to rely on anyone else or get beholden to anyone else. That would have been back in the late 70s or early 80s.
That advice served me very well.
I've never allowed myself to be taken advantage of, taken for a fool, abused in any way, etc.
I started working and saving during school holidays and weekend jobs, and then saved even more when I started having "proper" jobs after leaving school. I've always had more savings than my DH who literally had no savings at all when we first met as he was also low paid at that time. I sorted out my own private pension in the mid 80s when they were first widely introduced and have been contributing into it ever since. When I bought our home with DH, we put in half each for the deposit and set up a joint account where we both put in equal amounts for all the household bills. I still have my own savings, which continue to be higher than DH's even though he quickly qualified and became a similar earner to me a couple of years after we met.
As for jobs, I always made sure I had enough savings to "walk out" if the need arose, which happened twice. Once I walked out after being unfairly criticised by an incompetent boss for something I didn't do wrong. Just not going to put up with that. Second, was on the second day of a new job and I just didn't like the atmosphere and one of the bosses who showed her true colours as a bully on my first day. No thanks. Having the buffer of savings meant I didn't need to stay and suffer.
Same with men, at the first sign of any "bad" signs, I'd not hesitate to dump and not give them a second chance or listen to any excuses nor promises of improvements etc. Too much self respect to be treated like a doormat.
Same with tradesmen, car salesmen etc., I just won't be treated as the "little woman" and they soon feel my wrath if they try to patronise or intimidate me. They absolute hate it, say, when I tell a decorator whose screwed up some wallpapering, i.e. uneven tops/bottoms, mismatched joins etc that they have to do it again - they expect the "little woman" to be grateful and put up with it. No way!
What I can't understand is my sister, a couple of years younger who had the same upbringing, and presumably had the same "talk" with our parents, but she's the polar opposite, basically "fell" for the first lad who showed interest in her and ended up completely reliant on him, emotionally and financially, gave up her studies and chance of a good career to be "with him", and suffered a fairly miserable and controlled married life, entirely dependant on him, trapped by him, etc but she couldn't see it, or was in denial. It was almost their 25th anniversary before she finally saw sense and they separated and then divorced, but she'd lost all her prime years, came out of it with no money, now renting a tiny flat, no savings nor pension, etc.
So even if parents "teach" their daughters, there's no guarantee the person themselves will take heed, sadly.
