CookieDoughKid how do you actually teach children these things??
Personally, I don't know how possible it is to teach children some of these things. Children absorb so much from their environment - from what they see, hear, experience every day, that setting out to deliberately teach them these skills / give them these beliefs is really hard. Success breeds success.
From my experience, the 'wrong' messages I absorbed from my childhood were:
Work hard and get high marks because that is the most important thing.
Anything "business" related is a bit spivvy and people who do well in business are wide boys, chancers, use their gift of the gab to cover up for not being very clever. In my rural, lower middle-class upbringing I was surrounded by public sector workers (teachers, nurses etc) and farmers (a different category entirely!) / mechanics. The few relatives / parent's of friends that worked for big companies / banks / insurance companies OR had businesses of their own etc were considered (by my parents) to be frankly a bit common. I didn't know anyone at Uni who aspired to business or management. So I didn't even consider applying for any graduate training schemes etc when I graduated. The thought of working for a multi-national company was so far out of my experience I couldn't even contemplate it.
At the same time... don't aspire to "just" be a teacher / nurse or anything vocational / trades etc - which is what my parents were, as that's way below your potential: you are far too clever for this and it would be a waste of your intelligence.
I'm trying not to pass these ideas on to my children, but I worry that having seen DH (teacher) and me (admin) I'm repeating the circle. Schools are terrible at teaching most of the things that Cookie mentions.
However, what I am trying to teach / show my children is:
Confidence. I am a confident public speaker, I'm sociable and I enjoy networking, whether it's sociable or work-related. I didn't work for 10 years while my children were small, but during that time I took on a lot of voluntary work and became president of the (very small) charity for 5 years, running it in a very hands-on way. This meant that my children regularly saw me chairing meetings, organising and running big events, hosting meetings and planning sessions at home, and basically being out there in the public eye, getting involved, networking, multi-tasking etc.
Exposure to different ways of making a living, not just "worthy" ones. And that working in business is normal - not just for spivs! We deliberately chose to move abroad, so our children are growing up bilingual and bicultural: that's already a massive difference to my and DH's upbringing. They have friends from all over the world, and their parents mostly work in business / science / are entrepreneurs. We talk often about work - what different people do every day, and what they earn, and what skills are useful. Yes we encourage them to stick in at school, but we talk about how that's only the first step, it's only one box to tick, it gives you more choices about your future but it isn't the be all and end.
Public speaking / debating. If there was one thing I think would really help all children, it's learning to put together an argument and debate it in public. So many important skills and resilience can be learned there. There's a reason why the best independent schools put such a huge emphasis on this.
