1. Most people would never say bad things about parenting because it makes them look like demons. I basically tell my friends and colleagues that it is OK and I'm still not sure whether it worths it or not. That's as far honest as I'm willing, although it is pretty close to truth nowadays. I was a lot more snarky a year ago.
2. Humans are very good at adapting. If you told me 3 years ago that I have to go through all these, I'd never think about getting a kid. But somehow it actually feels OK now. And that's what I tell other people.
3. Having kids basically means having a completely different life style for me. I can see why some people actually feel so excited about it because their life style actually fit. It's about trading one life style to another, and this is something we rarely told others, who nevertheless never bother to ask anyway, because they don't know what to ask. Nowadays, I'd tell any young people to get their dreams done before getting a kid, unless they really really want it. You want to go travel the world? Do it before getting a kid. You want to teach yourself a long chain of Mathematics/Physics topics? Do it before getting a kid. I'm not saying you can't do them after having kids, but it's a LOT safer to do them before.
