At least for me I will say that disturbingly small number is probably good enough for practical purposes. All favorite thing, people, food are just snapshots in memory and revisiting them in physical world did not feel as great as my mind imagined.
I tried a few of those past favorite things and they were fine but nothing like best moments or some such. Same with people, neither they nor I am same person as before.
That almost sounds like you did not really enjoy raising your kids? I find that's a taboo thing to say, and if that's what you meant, I appreciate you saying so.
Like most things in life, there is a middle ground you know.
The physical act of creating a child is so easy many people do it by accident. Raising a child is an enormous task.
People from all walks of life have been raising children since, well, forever. Rich, poor, smart, dumb; nearly everyone figures it out.
There is A LOT of child neglect here in the states, and plenty of children literally do not make it out alive.
IMHO Kids aren't really "adults" till about 27-30 given the complexity of society. If you happen to have special needs kids, they will take even longer.
And there's the accent, which you'll never lose.
The best time to learn a language is between 0 and 10 y.o.
For people who already know English and aren't super into linguistics like you, the answer to "should I learn to speak x" is no.
The funny thing is that I spent some time working on my English accent, and it wasn't that hard. Grammar and common phrases are two difficult things that I still haven't mastered. The combination of these two factors causes me to sometimes get funny looks when people assume I'm probably a native speaker because I sound so similar, but make weird mistakes when I speak.
Now that I learn a third language (German), I put more effort into grammar and vocabulary but don’t really care about the accent. I’m not a native, deal with it.
