We convince ourselves that life will be better after we get married, have a baby, then another. Then we are frustrated that the kids aren't old enough and we'll be more content when they are.
After that, we're frustrated that we have teenagers to deal with. We will certainly be happy when they are out of that stage.
We tell ourselves that our life will be complete when our spouse gets his or her act together, when we get a nicer car, when we are able to go on a nice vacation or when we retire.

A farmer had some puppies he needed to sell. He painted a sign advertising the pups and set about nailing it to a post on the edge of his yard. As he was driving the last nail into the post, he felt a tug on his overalls. He looked down into the eyes of a little boy.
