In my mind age and this shift in focus are at least somewhat linked. 23 year old me would be pissed at 30 year old me for not moving to a FAANG company and instead focus on marriage, those 7 years did teach me a lot of important things about myself and the world.
My Wife comes from a country where getting married and having kids before the age of 20 was very much the norm at the time, which led to a lot of people having children at a time where they were not ready for that responsibility.
