I have a kid and act at least 10 years immature, if not much more. At least, that's the age group of people I mostly spend time with these days... when I spend time outside the house.

You'll probably be just as happy without kids, and some studies even suggest you might be happier. Being able to pursue your own interests is a nice luxury. This is among the reasons I say that we'll have an under population problem in the near future (within my lifetime, say 50 years). Children demand more sacrifice than most anything else. Becoming a doctor might take 8 years of school and 5 years of residency and cost a fortune, but there's no break in being a parent, and it lasts a lifetime if you're a good one.
