Absolutely, depends on the person really. Personally I find raising a child extremely boring and unfulfilling. For some it isn't. 95% of the people I know could have basically fit a child into their life by altering their schedules and priorities. If the things that actually brought your life meaning are absolutely incompatible with children, however, children are a much harder pill to swallow. You basically just have to wait down the clock until life resumes, because the only other 'option' is abandoning the child. Like a prisoner, I serve my 18 year sentence for the mistake I made -- it's no one else's fault but my own and now I have to live up to the commitment for the sake of the child.

I guess it's not surprising people have different tastes in activities in life.
