I only see a lot of young people trying to self-portrait themselves and trying to grasp everyone's attention. Egoism combined with proudness are at the beginning of each downfall...
Quoting: Theodesus Because parents alternated between neglecting them and spoiling them.
So the grow up emotionally needy, almost to a point of desperation, but they expect when they do get attention, all they get is intense and immediate attention and then basically told to go away again.
They don't know how to develop reasons for people to pay attention to them, like learning to play an instrument well, or being good in sport, or some other talent, nor do they learn to be genuinely independent.
I don't hold them in contempt, I feel really sorry for them. Many of them show signs of deep emotional trauma. I think they didn't get enough genuine mother's love as small children, only forced 'quality time' or given any toy they wanted by way of compensation.
Too many parents thought they could buy their kids instead of engaging with them.
