And another thing I understand is that some people actively want to raise children. You surely do. But I simply don't feel that way. Like, there's no inner sense of calling, or desire, or any moving thought or similar emotion or drive. Nothing like "yes, I want to do it".
And doing this not because I want it, but for the society's sake? It is an idea that makes sense, but but knowing the difficulties and stakes involved, a "why not" is pretty obvious to me. I most certainly don't want to spend significant resources of my lifespan on raising a kid I didn't even want. And thus I'm really glad that it's an option.
