"Nobody preaches about the sun coming up tomorrow. Nobody preaches about certainties. Believers preach about their world view not because they are certain, but because they are UNcertain"
I.E: What people like this are trying to do isn't convince you - it's to convince themselves.
If you choose another path, be it in work, decision to start or not start a family, from the mainstream you get pushback in many forms, because it's very hard for people to not want the choices that they make to be the _correct_ choices, and that must mean the _correct_ choices apply to everyone, right? We can all get trapped on the hedonic treadmill together!
There's a bit of this in the WFH/Office debate, too.
Best advice I ever got: If you want to be happier, get poorer friends.
