I think the point is (may be wrong, as I'm not the OP) is that people spend a lot of time getting uptight when their DCs are babies and toddlers posting about 'the right way to parent', as if there is some formula for all parents and all DCs and if you get it right and do all the right things you won't have the problems that people with teens or adult DC are posting about.
There is no 'right' way', what is right for one person and DC is wrong for another. If you are lucky you are well matched up with the parent and you look back and think of a situation that you think they handled really well, but your sibling may see it completely differently and harboured resentment for years.
Nature and nurture are both very important. I happen to think that nature is more important-but not everyone thinks the same. Even if it is more important you still need to nurture-you can't just opt out of parenting and leave them to find their own bedtime eat junk food etc!!
I would assume that OP comes from the sort of parent, who only has younger DCs, looks at difficult teenagers and thinks 'mine will never do that because I did x,y and z'. Irritating to those having the problem because they will have to wait 12 yrs or so to find it isn't that simple!
If you have unconditional love, security, clear boundries, good food, a good education, a 2 way communication, happy childhood memories then they will probably weather any storms that come their way. The difficult ones that I have known have come through to be perfectly reasonable adults!
Fast forward to the future, and I will be discouraging my children from going to university unless they need a degree for the job they want to do. I would just be happy that they find somethingthey want to do, tbh
On hindsight I would do the same.There is no point in just going to do a degree in your favourite subject.
