My own experience is that most people focus on the stresses, worries and overall negative(?) aspects. Maybe I've had it easy and I'm incredibly fortunate, which I often feel like, but after becoming a father I would tell you that all the stresses, worries and overall negative aspects are nothing, NOTHING, compared to the positives.

As I said in other comments, I'd never push anyone on such a personal topic, but I'll never forget how, right after my first was born, I simply wished parenthood on everyone.
