if you think your life is shit now, wait till you have an unpaid second job as a babysitter.
Seriously, whatever you think of kids, one thing is absolutely true: it's hard, it's very hard. Not in a poetic sense, but simply in terms of man-hours you will have to come up with.
Unless you live in a traditional patriarchal society, but if this were the case, you would probably have had several kids by now
