Having kids is a personal choice. The stress of having to support them is real and it might mean, at times, you sacrifice more than you would have without kids.

It's been entirely worth it for me and I cannot imagine my life without kids. But it's a deeply personal choice and I am not buying or selling the idea. I would just say nobody is ever ready and the fears around having them probably are more irrational than rational. But not wanting them because of how it might change your own life is a completely valid reason to not have kids.
