Xenia - I get where you're coming from - I think. I'm a soaring to the top kind of person myself, can't help myself loving work, being ambitious and having a career plan. But I was only chatting to a good friend today who's been a SAHM for 7 years, and my dp's been a SAHM for 4 years now, and neither of them have any real 'ambition' - no intention or desire to soar to the top, so both will be happy in the next year or two to get part-time jobs or re-train in something they enjoy, but will never earn huge amounts of money or probably work full-time. She said in a very matter of fact way that she (and dp) will never be like me and I'll never be like them. I started out being a bit offended but I know what she means.
Honestly, I find this at times frustrating, especially with dp, who went to Cambridge, has a brain the size of a planet, but not a single piece of ambition in her body.
It's tricky to understand and then be happy with other people's life choices that are different to yours - for you (and me), working full-time means something to us and therefore hopefully to our children - they'll be proud of us in a different way to the parents/carers who stay at home looking after them.
Flipping heck - I'm trying to think of how to word this post in a less bizarre way - but I know what I mean!
