One more thing is your career - you are helping people, building lives. That gives you a sense of purpose.

For some people, family gives them that sense of purpose. Building a little person's life. Watching them grow. Helping them succeed.

In a good family - family is always there for you. They see you thru the bad times, they are there for your weddings, graduations, birthdays, all that.

Might be hard to see that side of it if you come from a dysfunctional family or abuse history. But for many, that is what they want - the perfect little family where they can watch their kids grow up and lead successful lives.

Doesn't mean you HAVE to have kids to feel that way. Just the reason why some people do.
