I have been thinking about this recently.
Basically I was "on my own" once I was 17 (working, left home, completely independent). I was bright and academic but there was never any conversations about doing anything past "O" level. My mother had no further input. There was no encouragement, guidance, on matters to do with men, education, work, anything really.
I'm in my 50s now and I'm sorta OK, though there's been a lot of "sorting out" along the way. I am very independent minded and an independent thinker and probably a bit unusual in some ways! However, I suspect my life's been unnecessarily "hard" as a result. I do accept how my mother was, but I think the lack of support and guidance must have had an impact.
I suspect people who thrive best in life often have the combinations of talent and drive and luck - and parental support.
What do others think?
