I have everything on your list.
No mortgage, pension, ISAs for me, DH & all the kids. A few buy-to-lets all rented out.
I think I am confident and socially capable. I have a long list of letters after my name.
Only drink a few times a year. Ex smoker.
I run marathons. Have regular holidays that we plan a year in advance.
Have whole family get togethers generally once a month and for all kids' birthdays, Xmas etc.
Family are all educated, working 'top' jobs (think European MDs, doctors etc)
All my nephews and nieces are really well mannered and behaved. All (so far) have got top grades and are in top selective schools or RG universities.
Not myself but members of the family with MBE and Chairs of local organisations that work with Council/Police etc
However I don't go around talking or advertising any of this. (Maybe occasionally about my nephews and nieces but only cos I know how hard they work and I'm super proud of them).
No one knows anything about my financial situation and only my best friend knows we own other properties and that we don't have a mortgage.
Some people might know bits and bobs about our holidays or the family.
What NOBODY knows is the shit and stress that comes with having big families. People don't know the shit stirrer that is my SIL, or what a lazy ass my BIL is. No one hears about the arguments between the adults or the fights between the cousins, cos we all behave and save face in public.
What people do see is how bloody disorganised I am on a day to day basis. How I just about get through the day having fed the kids - cos I hate cooking and I'm disorganised. What a complete tip my house is pretty much everyday, cos again, I'm disorganised. My DC (primary age) are generally late to school. Occasionally even turn up without having done homework or their reading (shocking!!). I look young for my age and dress pretty casually too. You'll never see me on the school run in anything other than jeans and t shirt.
So many acquaintances and friends assume I'm younger than I am (I'm 39). I can tell that compared to them and other friends/mums on school run, I don't seem like an adult at all. If you met me, you wouldn't think I'm a proper grown up either I'm sure.
I look at certain friends of mine and envy their organised well-managed 'grown up' lives, because I know that that is what (in my opinion) I'm lacking the most.
My point is, don't measure yourself against anyone using those criteria. They are just one facet of a life, and gives you a very blinkered view of what someone is like.
