I'm only 19 now, so right now... no kids. But in the future, absolutely. Being a father will make me feel important on this world to at least two people (wife and kid) whereas, if I didn't have any children, I would not feel quite as important.
My dream would be to have kids at age 27, 28, 29, 40, and 41. That way I could raise three children up until they are about ready for middle school, and then I could do the whole thing all over again. I doubt my future wife would jump on board for such a plan. lol
Anyone who thinks kids are "black holes for money", congrats, you are a very shallow person and good luck finding somebody EXACTLY like you to marry; otherwise, you probably won't be getting married.
