I have an amazing kid and I love her and she's the light of my life and I wouldn't trade her for anything and all...
...but she is absolutely killing me and this is the hardest, scariest thing I've ever done in my life, and if anyone felt even one percent less than totally committed to parenthood then I would advise them not to do it. The idea of trying to convince somebody to create a human being that they would then resent, leading to at least two deeply fucked up lifetimes, is the stupidest goddamn thing imaginable.
There are plenty of people who want to have kids. Let 'em. Everyone else should do something they'd rather do instead.
