You're 20. Of course you don't want to have kids. Very few people at 20 want kids. I certainly didn't.

In fact, at 26, I was settled on being single for the rest of my life. I'm now 33, married, and have a 1 year old son. I laugh at my past self and understand how naive I was.

I'm not suggesting you'll be the same, just that you pay attention to the fact that you are seeing the world through the eyes of a 20 year old. :-)

You won't run into "the girl" though if you are standing still.
