I know just what you mean, though.
My labor dragged out for an eternity (I've told this story) and so when a friend of ours was pregnant with her first, we were telling her that we wished we would have stayed home longer, yadda yadda. So she listened to us a bit too well and barely made it to the hospital before the baby was born. (She was there, like, 20 minutes.)
Everyone's different.
