My 15 year old dd is happy, friendly, drama free, resilient and content. Id love to say its due to my amazing parenting, but I feel that quite a large part of it is due to her friendship groups and just her general nature.
At school she's well liked, i wouldn't say she's one of the popular kids, but she has the loveliest friendship group who all appear to be similar to her in temperament/behaviours. She's always been quite bright so doesn't struggle academically. School for her is a fun place to be.
She does do a sport, which gives her another friendship group out of school, and she has been teaching the younger kids for the past 2 years. This has massively helped her confidence in talking to strangers, public speaking, etc.
As a family we're generally quite calm, dh and i rarely argue, we're not strict, we don't really shout, we eat dinner together every evening, we ask for and value her opinions, so maybe that has given her a solid foundation?
But honestly, i couldn't pinpoint the reasons why she's so different to the hormonal mess i was at 15. Who knows if we've just been lucky so far, and she'll go off the rails in a year or two?
Unlike the examples in your post she does care to some extent what people think about her but its more in the context of for example having the "right" handbag for school or rolling up her skirt as thats what everyone does and she'd look like a lemon with it down to her knees. But i think teenagers do generally have traits of pack animals and feel the need to conform to the crowd to some extent.
