I agree, it does have more weight if you start your own family. But not everyone takes that route, and that is okay too. Not every person has the same path to meaning. I think the important thing is that as someone without children, I recognize and honor those who do, as they are doing something beautiful. It wasn't my path, but I support it. I'm not one of those idiot DINKs on social media trying to brag about how smart and free I am for not having kids. Those people are truly childish.
