This is a very interesting thread. I would like to add my observations if I may.
Upbringing has a huge impact on life-choices. I had a difficult and unpleasant childhood and that had a massive impact on me with regard to my twenties and thirties. Looking back now I am in my fifties, (and after extensive psychotherapy!) my life was total chaos, and I made terrible choices with regard to partners. I found myself in a dead end job, despite educating myself at night school etc, and even though I was a property developer living in freezing caravans while renovating dumps before that was even thought of on tv, I didn't reap the benefits I should have as was ripped off by (abusive) partners when we inevitably split up.
Luckily for some reason I seem to have a brain which automatically works out the best way to get value for my efforts, and a risk-taking and optimistic personality. I realised years ago that the way forward was to work for myself, and did that as well as holding down a job that paid the bills.
I have been very, very poor, and now that doesn't frighten me as I know that I can get out of that trap, and prosper by my own efforts.
Even though my childhood was horrible, I did learn something from my parents, (or was it the genes coming through?), as my family escaped from E Europe during and after WWII, and all have done well for themselves in the UK and abroad. They escaped without a pot to piss in as one of my Uncles says, and left behind property and land. But without exception they have all done well through shear graft.
Like Xenia, I have worked through pregnancies and back to work straight after the birth. I have taken some huge risks, and now in my middle age, some of them are beginning to pay off. If two risks in particular take off this year or next then the potential is huge.
I have no interest in money per se, but I am very driven, and I don't know where that has come from. I always have several irons in the fire, to spread that high risk a bit. I know I am different to most people I know, who never take any risks at all.
A lot of seemingly rich people I know have had their own businesses and then gone bankrupt, then started out again with no debt, and carry on other dubious business practices. I find that morally unacceptable, which is why it has taken me many years to get to the stage I am at now.
Sorry if that went on a bit, just my observations!
