Hah! They must be exceptionally wonderful people, then! ;-D
And which kid is the more successful? Who's counting? If your DD wants to maintain a happy relationship and make a home for her husband and kids, then it appears that she's pretty successful in that. I have learned that success isn't about wealth. It isn't about status or 'importance' or any tangible thing. It's inside you.
I've also learned that education is the most personal gift you'll ever get. It's for *you*, inside! It makes you a bigger, more rounded person and the more of it you get, the wider your horizons can be. But if you want a small horizon and really hanker to function within that, then you can be just as successful as Mr Gates or Ms Winfrey in your small pond.
I spent a lot of my life chasing qualifications for a place in the world that doesn't exist. I feel very lucky that happenstance has shown me where I *want* to be, not where I think I *ought* to be! To me, that's 'success'!
I have a friend who had a most ordinary academic career. Her academic record is about an inch thick, littered with FFs (Fail Forte) and withdrawals from courses. She squidged through her degree by the skin of her teeth and then couldn't get a job in her field (English and Psych). She took a part-time job as a secretary in the medical faculty at Uni, but didn't do frightfully well there because she couldn't really type efficiently. She was shifted around from pillar to post as a supernumary and wound up in the chancellery, processing enrolment applications.
Today, she's the Uni webmistress and head statistician. She is also solely responsible for the annual graduation ceremonies and is one of the best organisers I've ever known. She's one of those invaluable people who have a finger on every pulse and the knowledge to bring about seventeen separate processes together seamlessly. She's brilliant!
