I think this is a good filter (among many) that can inform someone if they want kids. There are places I go and do say, "damn, I'd love for me and my partner to have a kid and bring them here." If you don't hope for that, or if you do but aren't in a place to achieve that, by all means, don't have kids. But if you do, I'd recommend speaking with your partner(s) at least. There have been times in my life I never wanted kids. There have been times I wanted kids, but was open to not. Now I want kids. The important thing is to be true to yourself every step of the way, and communicate with people you trust along the way.
