Goodness that was far too long ago to remember, but no doubt it would have been a sim in a Maxis career type want. I know I had 2 siblings both achieve 20 best friends at uni back in 2007. I've played this game for ten years.

I haven't had one yet. I haven't been playing nearly as long as simsfreq -- only since November/December 2012 -- but I don't do anything to stop them reaching permaplat, in fact I think I try to help them, by giving them achievable LTWs and/or changing their careers to match their LTW. But nobody's got there yet. Maybe my unhurried aging-off playstyle takes the pressure off my Sims so they've time to enjoy their lives along the way. I think most of my Sims will have to be focused to achieve their LTWs but they don't have to be obsessed. There are other things in life.
I'm sure in time I'll have a few permaplat Sims, and I can think of a few likely candidates, but I really don't know who'll be first. I think I'll bookmark this thread and post again when somebody gets there.
Mine was a Fortune sim who reached the top of the Business career.
Because I play with aging off a lot and progress through ages slowly, since then I've download platinum aspiration slowing and fragile permaplat mods as it's kind of boring when they're permaplat. You feel as if there's nothing to work/aim for.
My Mum's simself yeeeeears ago when we use to play together. It was 'have 6 grandchildren'. Being that I made all 5 of my siblings as sims too, she easily ended up with more than 6 grandchildren. I think she ended up with double that.
You know, I think I would have had one back in base game if permaplat was a thing then. I remember making a sim have 10 children because she rolled the want to, that was chaotic! I had just discovered cheating and she had my first set of twins (cheated) followed by my first set of natural twins. That was quite the surprise! Although I remember sending the first twins to uni, so I must have installed that at some point... perhaps her LTW was not to do with children, or I stopped playing them before achieving it.
Virtually all of my sims go permaplat. If they have a career-based LTW it's almost a doddle, some of them have done it within ten days of turning adult (though some wouldn't have made it pre-elder without Elixir of Life). I've also achieved it with 50 Dream Dates and 50 First Dates, though that was much harder work than any career, and I've just had a sim go permaplat through 200 grilled cheese sandwiches.
I've never pursued the Marry Off 6 Children LTW because I don't want my population to spiral out of control. Though having said that, it was Kaylynn Langerak's LTW once I'd made her playable, so she and her partner adopted six kids. Only two of them ever married, so Kaylynn changed her aspiration to get a career-based LTW.
My big failure has been with the Golden Anniversary - several of my sims have tried for it, thrown an anniversary party and got a good memory of it, but never turned platinum. Presumably I'm doing something wrong.
It is a bit of work, but there is really no reason for not getting them all in permaplat. The career ones (especially knowledge sims) are, for me, the easiest, because they just have to study and often do not need a ton of friends to be promoted. In the beginning of my playing days, when permaplat became a feature, I would play one family until they were all permaplat, and moved on then!
So far, my first and only Sim to ever achieve a permanent platinum has been Sera Uliase. In all of my time playing this game, only one Sim that I'm aware of has achieve this! My playstyle usually doesn't focus too heavily on wants, or even lifetime goals to that extent. However, Sera achieved this status a few weeks ago, as she has successfully raised three children who have all graduated from university! I didn't even know that such a feat was awarded with a platinum status, so it was quite surprising!
Here is a picture of Sera when she was an adult; also with her loving husband Ralph...
