Musing about youngsters and resilience here. I realise anecdote is not data blah blah. During the time my two daughters were both at uni, one first year and one 3rd year they had to display extreme resilience. Their grandmother died, the dog had to be pts, their father diagnosed with stage 3 cancer, friend of one committed suicide plus lots of other normal life stuff. They both came through it, although yes they did ask for essay extensions etc, and they've both got 2:1s and full time jobs. I'm really proud of them, and they both have a work ethic. I suspect it's because they've seen their Dad and I always working, and coping with tit. I'm also quite an anxious person, but have tried to never let them see it, or certainly not until they were late teens.
But, I would say roughly half of their friends are the same, and the other half are the less capable variety for want of a better phrase. So I dont know whether it's nature or nurture, the ones who find it harder to cope seem to be the ones with less supportive parents - nothing to do with level of education or intellectual ability. Sorry, rambling!
