Right now, I'm focused on certain things involving my work more than anything else, but the right girl, having a child, raising a family aren't things that I'm going to arrange / plan around a career. They matter a lot more to me...sure you could plan and with strength of will get exactly what you want when it comes to having a kid say, but I find it a lot more rewarding to leave some room and see how things develop rather than plan human matters the way I plan things at work.
In terms of wanting a kid...currently, I don't really know, I don't go into 'awwww' mode when I see a kid, but neither do I find the cries, shit etc annoying. It just is. Happy enough around them.
Get those who are saying they don't want any. Many of those who are parents now shouldn't have been allowed to breed. Clearly, it's not something many can be 100 percent sure about before it happens, but if you do feel strongly against it, don't do it. There is the chance you could swing the other way once the kid's there, but the risk to the kid is simply not worth it.
Definitely easier for a guy, you don't get questioned much.
