There are goals aside from "raising a strong family", and some of them aren't related to raising a family at all.
It's a worthy goal, but if that's your only goal, you're missing out big time.
We exist for far more reasons than healthy procreation. In fact, I would say that's a place to start from, and your focus should be on accomplishing other goals.
It seems like a way to placate people into thinking that raising a healthy family is all that is really needed. That concept is completely false, as there is much more to our existence.
Each person has their own path. There is more than one correct answer.
