Windows are the lens through which we see the world. Dirt on the windows filters how we see what is out there.
Window cleaning is about changing what we see by transforming what we are looking through, not what we are looking at.
But the windows don’t stay clean for long. You’ll have to notice that they are getting dirty and clean them again in order to maintain the great view.
Similarly, keep your window – your perspectives – about your own life and marriage clean. Just like cleaning the windows, it requires regular maintenance to keep the view clear.
