Some of these examples are great - a pattern I see so much with my parent's generation is that they get locked into the same pattern of life. The same group of people, the same routines and the same hobbies for decades. I think that it's the natural path as we age - and you have to actively make choices to fight it if you don't want that.

However, there's only some aspects of life in which you truly have choice later in life. The cold hard truth of biology (especially female biology) is that probabilities of successfully having children start declining pretty quickly at a certain point.

And if you don't start saving for retirement early enough? You won't have a pension. If you don't buy a house when you're (relatively) young? At some point you'll find it very hard to get a mortgage.

It's great to write a relatively shallow piece about how you don't need to hit milestones so early - but that's a symptom of an underlying system which is increasingly disenfranchising young people and not giving them the opportunity to have ownership in society.
